It contains large blood vessels that supply the BRAIN and SPINAL CORD.Cerebral Palsy: A heterogeneous group of nonprogressive motor disorders caused by chronic brain injuries that originate in the prenatal period, perinatal period, or first few years of life. The four major subtypes are spastic, athetoid, ataxic, and mixed cerebral palsy, with spastic forms being the most common. The motor disorder may range from difficulties with fine motor control to severe spasticity (see MUSCLE SPASTICITY) in all limbs. Spastic diplegia (Little disease) is the most common subtype, and is characterized by spasticity that is more prominent in the legs than in the arms. Pathologically, this condition may be associated with LEUKOMALACIA, PERIVENTRICULAR.

Intraventricular meningiomas: MR imaging and MR spectroscopic findings in two cases. (1/146)

CT, MR imaging, MR spectroscopy, and angiography were performed in two men (ages 21 and 48, respectively) with intraventricular meningioma. In both cases, CT and MR imaging showed large tumors located in the trigone of the right lateral ventricle that enhanced intensely after contrast administration. MR spectroscopy was helpful in supporting a preoperative diagnosis of meningioma in both cases.  (+info)

Pineoblastoma showing unusual ventricular extension in a young adult--case report. (2/146)

A 19-year-old male presented with a 4-week history of headache. Neurological examination showed bilateral papilledema. Computed tomography revealed a pineal region mass with remarkable obstructive hydrocephalus. Magnetic resonance imaging showed a pineal region tumor continuously invading through the tectum into the cerebral aqueduct and the fourth ventricle with the preservation of the adjacent structures. The tumor appeared an iso- to hypointense mass on T1-weighted images, a heterogeneous iso- to hyperintense mass on T2-weighted images, and a heterogeneously enhanced mass after administration of contrast medium. Histological examination after endoscopic biopsy confirmed that the tumor was a pineoblastoma. Radiotherapy was given to the whole brain and the spinal cord, and magnetic resonance imaging showed complete remission of the tumor. Pineoblastomas are highly malignant tumors with seeding potential through the neighboring ventricle or along the meninges, and this type of tumor becomes larger with local extension. We found no previous reports of the continuous extension into the fourth ventricle. The present case showed ventricular extension with minimal mass effect to adjacent structures, and did not disturb ventricular configuration. According to the unusual finding of ventricular extension, this rare case of pineoblastoma requires adjuvant chemotherapy.  (+info)

Colloid cysts of the third ventricle: are MR imaging patterns predictive of difficulty with percutaneous treatment? (3/146)

BACKGROUND AND PURPOSE: Colloid cysts of the third ventricle are rare benign brain tumors. The purpose of this study was to correlate their patterns on MR images with the probability of success of percutaneous treatment. METHODS: Nineteen patients underwent endoscopic treatment for colloid cysts of the third ventricle. The cases were divided into two groups based on difficulty of the aspiration procedure. We reviewed CT scans and MR images and divided cysts into groups based on their signal intensity on the MR images and their density on CT scans. Intensity and density were correlated with difficulty of aspiration during the endoscopic procedure. RESULTS: The aspiration procedure was difficult in 63% of the cases. Eighty-nine percent of hyperdense cysts on unenhanced axial CT scans were categorized as difficult, and 75% of hypodense cysts were categorized as easy. On T2-weighted MR sequences, 100% of low-signal cyst contents were difficult and nearly 63% of high-signal lesions were easy. There was a significant correlation between the T2-weighted sequences and the CT scans regarding the difficulty of the aspiration procedure. CONCLUSION: T2-weighted MR sequences are useful for predicting difficulty of aspiration during stereotactic or endoscopic procedures. A T2-weighted low-signal cyst is correlated with high-viscosity intracystic contents.  (+info)

Isolated dilation of the trigono-inferior horn--four case reports. (4/146)

Four patients presented with isolated dilation of the trigono-inferior horn associated with either mass lesion at the trigone of the lateral ventricle or with shunt over-drainage. We investigated clinical symptoms, course, and neuroradiological findings of these cases. The pressure of the isolated ventricle was measured or estimated at surgery in all cases. The common symptoms were recent memory disturbance and contralateral homonymous hemianopia. Contralateral hemiparesis was observed occasionally. Rapid deterioration of the isolation caused uncal herniation in one case. Comma-shaped dilation of the inferior horn was observed in all cases. Midline shift was not conspicuous except in one case. Intraventricular pressure at surgery was 18 cmH2O, 35 cmH2O, 3 cmH2O, and within normal range. These cases had very similar clinical symptoms and neuroradiological findings. The pathophysiology of isolation suggested three types of isolation (high-, normal-, and low-pressure isolation), depending on the pressure of the isolated ventricle. The isolation of trigono-inferior horn is an important clinical entity as it may cause uncal herniation in patients with high-pressure lesions.  (+info)

Malignant spread of haemangioblastoma: report on two cases. (5/146)

Two cases are described in which, after successful removal of a cerebellar haemangioblastoma followed by several years of freedom from symptoms, there developed a progressive spinal cord compression, leading to death. At necropsy the spinal cords in both cases and the brainstem in one case, were irregularly plastered with haemangioblastoma. Although there was no doubt that malignant spread had occurred from one or more primary tumours, the histology of the tumour tissue was in no way different from that of conventional haemangioblastoma.  (+info)

Increased conspicuity of intraventricular lesions revealed by three-dimensional constructive interference in steady state sequences. (6/146)

We describe our preliminary experience with the three-dimensional constructive interference in steady state (3D-CISS) sequence for the evaluation of intraventricular lesions. Cyst walls, extent and margins of tumors, and intratumoral cystic structures were clearly depicted on 3D-CISS images. The 3D-CISS sequence can offer additional information to conventional MR studies to define intraventricular lesions better.  (+info)

Ependymoma with extensive lipidization mimicking adipose tissue: a report of five cases. (7/146)

Lipomatous ependymoma is a recently described entity and only 3 cases of this variant have been reported in the literature. We report 5 cases of this rare variant of ependymoma. Patients age ranged from 4 years to 45 years and, interestingly, all of them were males. Two tumors were supratentorial in location, 2 in the fourth ventricle and 1 was intramedullary. Microscopically all of them showed the classical histology of ependymoma along with lipomatous differentiation. The lipomatous component was composed of cells with a large clear vacuole pushing the nucleus to the periphery and giving a signet ring cell appearance. This component demonstrated positivity for GFAP and S-100 protein thereby confirming its glial lineage. Three of the 5 tumors were high grade (WHO-grade III), had a high MIB-1 labelling index (MIB-1 LI) and showed recurrence on follow-up. However, 2 were low grade (WHO grade II) and patients are free of disease till the last follow up.  (+info)

Intraventricular cryptococcal granuloma. (8/146)

A case is reported of a cryptococcal granuloma occurring within the lateral ventricle. The findings on angiography and brain-scanning led to a preoperative diagnosis of intraventricular meningioma. There are no previous reports of an isotope brain-scan in this condition and angiography usually shows an avascular swelling.  (+info)

Intraventricular tumors can be categorized into those that originate from structures within the ventricular system or those that arise from the ventricular wall and subsequently grow into the ventricle (2, 11). Choroid plexus tumors and meningiomas are typical examples of tumors arising from an intraventricular structure, the choroid plexus (12, 13). By contrast, intraventricular gliomas likely originate from a paraventricular location before growth into the ventricle. Regardless of origin, a tumor is considered intraventricular if it is located primarily within the ventricular system and causes a local expansion of the ventricle with growth. Most lateral ventricular tumors enlarge slowly and typically do not cause symptoms until reaching a size large enough to cause obstructive hydrocephalus or compression of surrounding eloquent structures (4, 5). The most common symptom is headache, followed by visual deficits and signs of elevated intracranial pressure, including papilledema (2, 4, 11, 12, ...
A 23-year-old primigravida presented to her local hospital with reduced fetal movements at 31 week of gestation. An admission cardiotocograph showed sinusoidal pattern. An ultrasound (US) revealed a brain abnormality with a mass. An US at the regional Fetal Medicine unit confirmed a hydropic fetus, with an intracranial mass measuring 6.6×7 cm in the right lateral ventricle (possibly haemorrhagic), ventriculomegaly and loss of anatomical landmarks in the brain. Antenatal MRI scan confirmed a 7 cm mass with appearances suggestive of an intraventricular tumour, possibly choroid plexus papilloma or carcinoma. Following counselling by the multidisciplinary fetal medicine team the couple opted for termination of pregnancy and a vaginal delivery, the first such report in the literature. Cephalocentesis was performed following fetocide to reduce the hydrocephalus. Postmortem, histology, cytology and immunohistochemistry confirmed a Glioblastoma (WHO Grade IV).. The incidence of brain tumours in first ...
The right and left lateral ventricles are structures within the brain that contain cerebrospinal fluid, a clear, watery fluid that provides cushioning for the brain while also helping to circulate nutrients and remove waste. Along with the structures known as the third ventricle and the fourth ventricle, the lateral ventricles
Tumors that arise within the ventricles present a unique surgical challenge. Because of their deep location, relatively large size, and their association with hydrocephalus, surgical planning requires a careful assessment of the optimal method to access the lesion and to provide adequate exposure for tumor resection. The transcallosal approach to the lateral ventricles often is the best procedure by which to achieve these goals.. Partial sectioning of the corpus callosum does not cause significant neurological deficits; however, if the surgery induces additional brain injury, the neurological deficits can be more severe in the presence of a callosotomy. Knowledge of the techniques of transcallosal surgery and careful preoperative planning can reduce the risk of permanent neurological impairment; these range from protection of the cortical veins that drain into the superior sagittal sinus to brain relaxation and ventricular drainage, as well as proper identification of anatomical landmarks within ...

Neurocytoma tumors are relatively homogeneous, including cells almost entirely of neuronal antigenicity. Both in vivo and in vitro, neurocytoma cells divide and expand to generate proneuronal progeny that express musashi and βIII-tubulin, an expression pattern similar to the neuronally committed transit amplifying progenitors of the adult subependyma. Some mature to express the Hu proteins as markers of postmitotic neurons, although the low incidence of Hu+ cells in neurocytoma suggests that postmitotic neurons generated within these tumors die quickly after their genesis. When removed from the subependymal environment to culture, neurocytoma cells expressed E/nestin:GFP, divided in response to bFGF, and generated neurospheres, which in turn gave rise to both neurons and astrocytes. The high incidence of neurospheres arising from native neurocytoma cells, ,11%, suggested that the dominant musashi+/βIII-tubulin+ proneuronal cells of the neurocytoma were individually capable of regenerating ...
FINAL DIAGNOSIS: INTRAVENTRICULAR SCHWANNOMA (WHO GRADE I).. DISCUSSION:. Schwannomas account for up to 8% of intracranial neoplasms (14). The vast majority of cases arise from the cranial nerves, with the 8th nerve being most commonly involved (14). Rare cases of schwannomas may develop as primarily meningeal, intracerebral or intraventricular tumors (14). In a review of the literature, we found that only few cases of intraventricular Schwann cell tumors have been reported so far (1,4-9,12,13). These tumors were generally located in the lateral or fourth ventricles. To our knowledge, the tumor of our patient is the first reported schwannoma of the third ventricle.. The origin of intraventricular schwannomas is unknown. However, similar to the hypotheses about the histogenesis of spinal intramedullary (3) and intracerebral schwannomas (11), which are slightly more common than intraventricular schwannomas, different possibilities may be considered. Schwannomas may arise from the sympathetic nerve ...
The adult mammalian brain retains niches for neural stem cells (NSCs), which can generate glial and neuronal components of the brain tissue. However, it is barely established how chronic neuroinflammation, as it occurs in neurodegenerative diseases, such as Alzheimers and Parkinsons disease, affects adult neurogenesis and, therefore, modulates the brains potential for self-regeneration. Neural stem cell culture techniques, intraventricular tumor necrosis factor (TNF)-α infusion and the 6-hydroxydopamine mouse model were used to investigate the influence of neuroinflammation on adult neurogenesis in the Parkinsons disease background. Microscopic methods and behavioral tests were used to analyze samples. Here, we demonstrate that differences in the chronicity of TNF-α application to cultured NSCs result in opposed effects on their proliferation. However, chronic TNF-α treatment, mimicking Parkinsons disease associated neuroinflammation, shows detrimental effects on neural progenitor cell activity.
Central neurocytomas are rare brain tumors occurring in young adults and usually located in the cerebral ventricles. These neoplasms account for 0.25% to 0.5% of all intracranial tumors.6 EVNs can be called central neurocytoma-like tumors. They are more unusual tumors with biologic behavior and histopathologic characteristics similar to the neoplasms that occur in the lateral ventricles.1-3,7 EVNs seemed to exhibit a somewhat larger morphologic spectrum compared with intraventricular neurocytomas. The fourth edition of the WHO classification of tumors of the central nervous system, published in 2007, listed EVN as a new entity.1 Case reports have documented involvement of the cerebral hemispheres (commonly the frontal lobe followed by the parietal lobe), thalamus, cerebellum, pons, amygdala, pineal gland, and spinal cord.2-6,8,9 EVNs generally manifest through mass effect in the form of seizures and hemiparesis. Few imaging findings have been reported, mostly in case reports. The largest series ...
Background: Patients with hippocampal epileptogenic foci may benefit from targeted intracranial monitoring of seizures and treatments such as hippocampal electrical stimulation, closed-loop stimulation, and stereotactic laser ablation. Each may benefit from a greater volume of hippocampal coverage with long-axis cannulation. Furthermore, an extraventricular trajectory avoids brain shift and reduces the risk of hemorrhage from ependymal…

In the background of HIV, cerebral atrophy is typically present. Lesions most commonly are located in the cerebral hemispheres and deep gray nuclei. The degree of enhancement of the lesions may be poor, reflecting the immune status of the patient.. ...
Aims/hypothesis: The present study was conducted to evaluate the effects of central administration of melanotan II (MTII), a melanocortin-3/4 receptor agonist, on hepatic and whole-body insulin sensitivity, independent of food intake and body weight. Methods: Over a period of 24 h, 225 ng of MTII was injected in three aliquots into the left lateral ventricle of male C57Bl/6 mice. The animals had no access to food. The control group received three injections of distilled water. Whole-body and hepatic insulin sensitivity were measured by hyperinsulinaemic-euglycaemic clamp in combination with [3H]glucose infusion. Glut4 mRNA expression was measured in skeletal muscle. Results: Plasma glucose and insulin concentrations under basal and hyperinsulinaemic conditions were similar in MTII- and placebo-treated mice. Endogenous glucose production (EGP) and glucose disposal in the basal state were significantly higher in MTII-treated mice than in the control group (71±22 vs 43±12 μmol·min-1·kg-1, ...

The purpose of this report was to review the results of stereotactic radiosurgery in the management of patients with residual neurocytomas after initial resection or biopsy procedures. Four patients underwent stereotactic radiosurgery for histologically proven neurocytoma. Clinical and imaging studies were performed to evaluate the response to treatment.. Radiosurgery was performed to deliver doses to the tumor margin of 14, 15, 16, and 20 Gy, depending on tumor volume and proximity to critical adjacent structures. More than 3 years later, imaging studies revealed significant reductions in tumor size. No new neurological deficits were identified at 53, 50, 42, and 38 months of follow up. The authors initial experience shows that stereotactic radiosurgery appears to be an effective treatment for neurocytoma. ...

FINAL DIAGNOSIS. Chordoid glioma of the third ventricle WHO 2007 grade II. DISCUSSION. Chordoid glioma is a rare tumor of the third ventricle, firstly proposed as a distinct entity by Brat et al in 1998 (1). To our knowledge (December, 2011), 74 cases (including our case) have been reported. The tumor predominantly occurs in adult women with a female to male ratio of 1.6 to 1 and the mean age at presentation at 45.25 years of age. Most patients have headache, visual symptoms, and memory disturbances. Other symptoms are lethargy, somnolence, endocrine disturbance such as hypothyroidism and diabetes insipidus, and symptoms caused by space occupying lesion and obstructive hydrocephalus are also observed in some patients. Chordoid glioma mainly locates at the third ventricle or nearby structures, hence the name "Chordoid glioma of the third ventricle". Unusual locations without third ventricular association that have been reported are parieto-temporal region (3) and thalamic pulvinar area (5). The ...
Cerebellar neurons are generated from two germinal neuroepithelia: the ventricular zone (VZ) and rhombic lip. Signaling mechanisms that maintain the proliferative capacity of VZ resident progenitors remain elusive. We reveal that Sonic hedgehog (Shh) signaling is active in the cerebellar VZ and essential to radial glial cell proliferation and expansion of GABAergic interneurons. We demonstrate that the cerebellum is not the source of Shh that signals to the early VZ, and suggest a transventricular path for Shh ligand delivery. In agreement, we detected the presence of Shh protein in the circulating embryonic cerebrospinal fluid. This study identifies Shh as an essential proliferative signal for the cerebellar ventricular germinal zone, underscoring the potential contribution of VZ progenitors in the pathogenesis of cerebellar diseases associated with deregulated Shh signaling, and reveals a transventricular source of Shh in regulating neural development.. ...

The third ventricle is one of the four ventricles in the brain that communicate with one another. As with the other ventricles of the brain, it is filled with cerebrospinal fluid, which helps to protect the brain from injury and transport nutrients and waste.
This approach targets the anterior segment of the third ventricle, the region between the optic chiasm and the foramen of Monro. Gentle manipulation of neurovascular structures is imperative during surgery of the third ventricle. Pial transgression should be avoided along the walls or floor.

Choroid plexus papillomas are low grade tumors that arise from the intraventricular CSF-producing choroid plexus. Here we see the transition from the round bland nuclei and ample pink cytoplasm of the normal choroid plexus epithelium (bottom of image) to the dysplastic columnar epithelium of the papilloma (top of image) featuring nuclear crowding and mitotic activity…
Answer: Choroid plexus papilloma. Histology: This papillary neoplasm is composed of delicate fibrovascular stalks that are lined by a single layer of bland appearing cuboidal to columnar epithelium with round to oval, basally situated monomorphic nuclei. No mitotic figures are readily identified. These features are diagnostic of a choroid plexus papilloma. Discussion: Choroid plexus tumors make up less than 1% of all brain tumors, but they represent 2-4% of brain tumors in children, and 10-20% of brain tumors in the first year of life. In general, choroids plexus papillomas are five times more common than choroids plexus carcinomas. Approximately 80% of choroid plexus carcinomas arise in children representing 20-40% of pediatric choroid plexus tumors. The majority of choroids plexus tumors arise in the lateral ventricle (50%), followed by the fourth (40%) and third ventricles (5%).. Histologically, the differential diagnosis of choroids plexus papilloma includes villous hyperthrophy (diffuse ...

Postoperative imaging important: The first postoperative imaging should be done within 72 hours to make sure there is no residual tumor or to assess its size if tumor remains. Follow-up imaging will then depend on the pathology of the tumor and on the adjuvant therapies (typically every 3 months for choroid plexus carcinomas; and every 6 months, then every year for choroid plexus papillomas ...
ICH obstruction of third ventricle was defined as third ventricle compression on 1 or more axial computed tomography slices visually impeding cerebral spinal fluid flow. If the third ventricle was casted with IVH, it was scored as such. Multivariable logistic regression analyses were used to determine whether obstruction of the third ventricle predicts poor functional outcomes defined as modified Rankin score (mRS) 4-6, higher mRS, and mortality at 180 days. Models were adjusted for thalamic ICH location, ICH volume, IVH volume, age, hydrocephalus, baseline Glasgow coma scale, and percentage of low cerebral perfusion pressures during treatment.. ...
Hydrocephalus. Hydrocephalus is a condition in which there is either an obstruction to the flow of CSF within the ventricular system or subarachnoid space (noncommunicating hydrocephalus) either due to intraventricular mass lesions or to external compression or a problem with reabsorption of CSF (communicating hydrocephalus). The type of hydrocephalus that occurs with SAH is communicating hydrocephalus. Hydrocephalus can be classified as acute, subacute, or delayed. The profiles for each are different and are briefly discussed here. With SAH, hydrocephalus develops as a result of blood in the CSF, which plugs the arachnoid villi, thus interfering with the reabsorption of CSF. Diagnosis is established on the basis of CT findings, which will reveal dilated ventricles with blood within the ventricles.. Signs and Symptoms/Treatment. The following summarizes the signs and symptoms of the three types of hydrocephalus, as well as the appropriate treatment for each.. ACUTE. ...

Tyr-Pro-N-MePhe-D-Pro-NH2 (1.86 nmol), dynorphin A1-17 (4.65 nmol) and DPDPE (4.64 nmol), which are selective for mu-, kappa- and delta- opioid receptors, respectively, were injected into the right lateral ventricle of unrestrained male Sprague-Dawley rats. At ambient temperatures of 30 degrees C and 5 degrees C, brain surface temperature (Tb), oxygen consumption (VO2) and heat exchange (Q) were measured for 3 hr after injection in a gradient-layer calorimeter. Tyr-Pro-N-MePhe-D-Pro-NH2 at 30 degrees C caused significant hyperthermia (1.39 +/- 0.48 degree C) with onset occurring 15 to 30 min after injection and lasting 60 min after injection. Increased Tb was due to a significant decrease in Q (-1.31 +/- 0.31 cal/g/hr) and to a 60 to 75% increase in VO2 compared with saline controls. Thirty-min pretreatment with cyclic D-Phe-Cys-Tyr-D-Trp-Arg-Thr-Pen-Thr-NH2 (0.74 nmol), a mu-selective antagonist, blocked the changes. At 30 degrees C, neither dynorphin A1-17 nor DPDPE significantly altered Tb, Q ...
depression is an evolutionary adaptation that emerged where displaced dominants needed to make a transition to lower social status and that is now triggered, in those individuals that have this adaptation, by damage to reproductive potential from any source. The behavioural cluster associated with depression includes adoption of a hunched posture, avoidance of eye contact, loss of appetite for food and sex and sleep disruption. This behavioural cluster serves to reduce an individuals attack provoking stimuli and so facilitates this social change. When viewed in this context, it becomes clear that many of the brain areas that mediate these behaviours (e.g. the pineal, hypothalamus and amygdala, whose main output, the stria terminalis passes through) all lie in close physical proximity to the third ventricle. In consequence, it is proposed that depression has its origins within this ventricle. Disruption of circadian rhythms, appetite for sex and food and fear/defence responses would all ensue if ...

Each lateral ventricle has three horns also called cornus. They can be referred to by their position in the ventricle, or by the lobe that they extend into. The anterior horn of lateral ventricle or frontal horn, passes forward and to the side, with a slight inclination downward, from the interventricular foramen into the frontal lobe, and curves around the front of the caudate nucleus. Its floor is formed by the upper surface of the reflected portion of the corpus callosum, the rostrum. It is bounded medially by the front part of the septum pellucidum, and laterally by the head of the caudate nucleus. Its apex reaches the posterior surface of the genu of the corpus callosum. The posterior horn of lateral ventricle or occipital horn, passes into the occipital lobe. Its direction is backward and lateralward, and then medial ward. Its roof is formed by the fibers of the corpus callosum passing to the temporal and occipital lobes. On its medial wall is a longitudinal eminence, the calcar avis ...
INTRACRANIAL COMPLICATIONS 359 to the extradural abscess. More rarely the abscess is due to septic infection of one of the pial veins of the temporal lobe or cerebellum. Infection by this route, which is common in cases of acute middle ear suppuration, may result hi multiple abscesses and meningitis. Once it has formed, a brain abscess tends to expand at the expense of the white matter, which has less vascularity than the grey.

Transcranial Doppler ultrasonography is usually used in the evaluation and management of patients with brain injury. This noninvasive method measures local blood flow velocity and direction in the proximal portions of large intracranial arteries. The operator requires a short training and experience to perform. The third ventricle diameter measurement by transcranial duplex flow sonography was performed in healthy volunteers . This studies show similar results in those obtained with the MRI or Computer Tomography (CT). Currently the third ventricle diameter measurements by transcranial Doppler ultrasonography was not validated for neuro-intensive care unit patients. The investigators propose to used recent ultrasound system to validate the third ventricle diameter measurements in comparison with the standard method (CT ...

Hemangioblastoma (HB) in the supratentorial region of the brain is rare and only a few cases are reported on intraventricular HB. HB of the lateral ventricles is even rarer. We present a case of a 30-year-old man with generalized tonic clonic seizures. The brain computed tomography showed a 5.5 cm heterogeneous mass extending into both lateral ventricles with partial enhancement. Based on the size and imaging features, we present the fourth documented case of a large solitary intraventricular HB. Our approach to this unique case and some treatment complexities are also described.Considering the rarity of the case and the patients imaging features, the present study provides a better understanding of HB and recommends HB to be considered in the differential diagnosis of masses in the lateral ventricles. In addition, some preventable pitfalls in the treatment of such complex cases are described.

A tiny enhancing mural portion of the fourth ventricle in MRI suggested that the cyst was hemangioblastoma, but pathological evidence showed that the cyst was in fact NE cyst in the fourth ventricle. In order to make proper decision on to what extent of surgical resection should be done, considering every possibility in differential diagnosis might be helpful. This case reports an unusual pathology in 4th ventricle, considering the patients age, and demonstrates that a rarer disease may share radiological features of a common disease ...
The ventricular spaces in the various subdivisions of the brain reflects the fact that the ventricles are the adult derivatives of the open space of the embryonic neural tube. The two lateral ventricles, situated within the cerebrum, are relatively large and C-shaped, and roughly wraps around the dorsal aspects of the basal ganglia. In the lateral ventricles of the embryo the successive generation of neurons gives rise to the 6-layered structure of the neocortex, constructed from the inside out during development. ...

Glioblastoma represents 15%-20% of all intracranial tumors and approximately 50 % of gliomas in adults. Although capable of arising anywhere in the central nervous system, these tumors mainly present as a frontotemporal lesion (63%) of the cerebral cortex. But, intraventricular glioblastoma is rare and only few cases have been reported in the literature. We report a case of 40-year-old woman who had a headache, vomiting and visual disturbances that persisted for four weeks. Magnetic resonance imaging showed an intraventricular lesion with inhomogeneous enhancement and infiltrative borders. These characteristics are consistent with other differential diagnoses: carcinomas, ependymomas and choroid plexus papillomas. The patient underwent a stereotactic biopsy allowed the final diagnosis of intra ventricular glioblastoma.

Hyponatraemia following aneurysmal subarachnoid haemorrhage is associated with an increased risk of cerebral infarction. Whether the development of hyponatraemia was related to enlargement of the third ventricle on the admission CT scan was investigated in a consecutive series of 133 patients who were seen within 72 hours of aneurysmal haemorrhage. Hyponatraemia occurred significantly more often in patients with enlargement of the third ventricle (with or without dilatation of the lateral ventricles) than in patients with a normal ventricular system (20/41 versus 24/92, p = 0.016). After ventricular drainage, the sodium levels returned to normal in two patients in whom the size of the third ventricle decreased and not in four patients with persistent enlargement of the third ventricle. The significant relationship between enlargement of the third ventricle and hyponatraemia remained after adjustment for the amount of cisternal blood, but not after adjustment for the amount of intraventricular ...

The ventricular system of the brain has been since its discovery divided into four, the two lateral ventricles, the third and connected by a small tube, the fourth. Herophilus placed the soul in the fourth ventricle and the animal spirits (intellectual, motor system) in the brain itself (cerebrum). Taking information available from Herophilus concerning the ventricular localization of the soul and the concepts elaborated by Galen, a doctrine emerged which explained the function of the mind. This Cell Doctrine localized the mind to the ventricular system of the brain. The two lateral ventricles were considered to represent the first cell, the third ventricle the second and the fourth ventricle the third. information was synthesized in the back part of the first cell or in the second cell to form imaginativa (imagination) and fantasia (fantasy). The second cell was also the seat of reasoning. Words used for function processing in this cell included aestimativa (judgement), cognitativa ...
... or choroid plexus tumor is a type of cancerous tumor that occurs in the brains choroid plexus tissue and most often occurs in children. The choroid plexus tissue lines the ventricles of the brain and produces cerebrospinal fluid or CSF. CSF circulates around the brain and spinal cord providing cushioning and protection. Because these tumors arise from the tissue involved in the making of CSF, the tumors can spread widely through this fluid. Symptoms of choroid plexus carcinoma are similar to those of other brain tumors including frequent headaches, unusually large head due to excess fluid on the brain, or large "soft spots" found on the babys head. Other symptoms may include a decrease or loss of appetite and vomiting. The cause behind these tumors is largely unknown.. Treatment is usually surgical removal of the tumor and if removed completely, may be the only treatment necessary. If the recurs, a second surgery along with radiation and/or chemotherapy may be needed. ...
Responsive nerve stimulation (RNS) represents a safe and effective treatment option for patients with medically refractory temporal lobe epilepsy. In cases of long intraparenchymal course and posterior-anterior electrode direction through occipital burr holes, disciplined stereotaxy is essential for stimulation of the appropriate target.

An O-arm spin was performed after the placement and the images obtained were fused to the preoperative CT images. It demonstrated curvature of the leads, with some deviation from the planned trajectory, but no deviation from the target, that was worse on the left side, compared to the right; the left lead was placed first, followed by the right lead.

BACKGROUND. Hemangiopericytoma (HPC) is a rare vascular tumor, and pathologic distinction from synovial sarcoma and solitary fibrous tumor is a significant problem due to shared histologic features. In the current report the authors defined the clinical behavior and prognosis for patients with HPC. METHODS. Between July 1982 and February 1998, 62 patients with a diagnosis of primary, recurrent, or metastatic HPC were identified from a prospectively maintained database. The pathology of all cases for which material was available (57 cases) was re-reviewed for histologic confirmation of the HPC diagnosis. Using strict pathologic criteria, including immunohistochemistry and electron microscopy, tumors from 25 of 57 patients qualified for the diagnosis of conventional hemangiopericytoma; those tumors formed the basis of the current report. Survival was determined by the Kaplan-Meier method. RESULTS. At the time of initial presentation, 19 patients had primary tumors, 3 had locally recurrent disease, and 3
Background The ventricles.

There are two lateral ventricles, located on each of the brain hemisphere. The fluid from both lateral ventricles enters the 3rd ventricle, then passes through a narrowing, the aqueduct…
Recognized as a pioneer in his field, Phoenix, AZ, brain surgeon Dr. Peter Nakaji can remove colloid cysts with minimally invasive keyhole brain surgery.
The brain ventricular system is essential for neurogenesis and brain homeostasis. Its neuroepithelial lining effects these functions, but the underlying molecular pathways remain to be understood. We found that the K channels expressed in neuroepithelial cells determine formation of the ventricular system. The phenotype of a novel zebrafish mutant characterized by denudation of neuroepithelial lining of the ventricular system and hydrocephalus is mechanistically linked to Kcng4b, the homologue of the "silent" voltage-gated K channel alpha-subunit Kv6.4. We demonstrated that Kcng4b modulates proliferation of cells lining the ventricular system and maintains their integrity. The gain of Kcng4b function reduces brain ventricles. Electrophysiological studies supported an idea that Kcng4b mediates its effects via an antagonistic interaction with Kcnb1, the homologue of the electrically active delayed rectifier K channel subunit Kv2.1. The mutation of kcnb1 reduces the size of ventricular system and ...
BADEMCI, G. et al. Late dissemination of ependymoma: case report. Neurocirugía [online]. 2007, vol.18, n.4, pp.333-336. ISSN 1130-1473.. Spinal cord dissemination over 10 years after surgical removal of the fourth ventricle ependymoma without local recurrence is extremely rare. A 49-year-old male underwent a macroscopically gross total emoval of the fourth ventricle ependymoma and postoperative radiothe rapy to the posterior fossa. Twelve years after the initial operation, the patient complained from uncontrolled fever attacks, low back pain and numbness of the legs. Spinal Magnetic Resonance Imaging revealed intradural extramedullary mass lesions located at the thoracic 2-3 and lumbar 5 vertebrae levels. Cerebrospinal fluid exami nation showed no tumour cells. He underwent total excision of these spinal lesions. Although the majority of the recurrences take place within a few years after surgery, we experienced a case with multiple spinal disseminations 12 years after the resection of the ...
