Paroxysmal kinesigenic choreoathetosis associated with frontotemporal arachnoid cyst--case report. (1/167)

A 17-year-old male presented with paroxysmal kinesigenic choreoathetosis (PKC) associated with frontotemporal arachnoid cyst. Xenon-133 single photon emission computed tomography detected a slight but equivocal decrease in regional cerebral blood flow in the vicinity of basal ganglia associated with the PKC episodes. PKC continued after surgical removal of the cyst but was well controlled by oral administration of carbamazepine. Whether the pathogenesis of symptomatic PKC was associated with the cortical lesion could not be determined in the present case.  (+info)

Heading injury precipitating subdural hematoma associated with arachnoid cysts--two case reports. (2/167)

A 14-year-old boy and a 11-year-old boy presented with subdural hematomas as complications of preexisting arachnoid cysts in the middle cranial fossa, manifesting as symptoms of raised intracranial pressure. Both had a history of heading the ball in a soccer game about 7 weeks and 2 days before the symptom occurred. There was no other head trauma, so these cases could be described as "heading injury." Arachnoid cysts in the middle cranial fossa are often associated with subdural hematomas. We emphasize that mild trauma such as heading of the ball in a soccer game may cause subdural hematomas in patients with arachnoid cysts.  (+info)

Lumbosacral extradural arachnoid cysts: diagnostic and indication for surgery. (3/167)

No critical discussion of the indication for the surgical treatment of lumbosacral extradural arachnoid cysts is found in the literature. Therefore, we want to compare the results in patients with operative and conservative treatment to define standards for a good surgical result. Over a period of 9 years, we operated on eight patients with a lumbosacral extradural arachnoid cyst and treated eight others conservatively. Only three of the operated patients experienced a postoperative relief of pain, but none was symptom free. The only one with continuing success had a preoperative history of 1 year only. MRI scans without contrast agent were misinterpreted in one included and one excluded case. The results of conservative treatment were nearly the same as those of operative treatment. MRI is the best diagnostic tool, but a variety of sequences must be used. Patients with a short pain history and a clear neurological deficit profited most from surgery. Patients with slight and not clearly related uncharacteristic symptoms should be excluded from surgery.  (+info)

Intracerebral cystic meningioma--case report. (4/167)

A 46-year-old female presented with persistent bifrontal headache. Computed tomography revealed a large cystic tumor in the right temporoparietal area, which included a solid component. The tumor had no attachment to the dura. There was no peritumoral edema or mass effect usually found around cystic meningiomas. The solid component was totally removed. Histological examination indicated that the tumor was a fibrous meningioma. Intracerebral meningioma with a large cystic component without dural attachment should be considered in the differential diagnosis of cystic cerebral tumors.  (+info)

Intracystic hemorrhage of the middle fossa arachnoid cyst and subdural hematoma caused by ruptured middle cerebral artery aneurysm. (5/167)

We report a case of a cerebral aneurysm arising from the bifurcation of the left middle cerebral artery that ruptured into a left middle cranial fossa arachnoid cyst, associated with acute subdural hematoma. We discuss the relationships of aneurysm, arachnoid cyst, and subdural hematoma.  (+info)

The role of endoscopic fenestration procedures for cerebral arachnoid cysts. (6/167)

Recently, endoscopic procedures have been recommended as the first surgical option for cerebral arachnoid cyst (AC). The author reports seven ACs treated endoscopically and discuss the role of endoscopic fenestration. The age of the patients ranged from two to 62 years. Three ACs were located in the posterior cranial fossa, two in the suprasellar area, one in the middle cranial fossa, and one in the convexity. All cases were examined by cine magnetic resonance (MR) flow study. The patient's symptoms included headache, vomiting, dizziness, problems in balance, visual disturbance, and seizure. The author performed a cysto-cisternostomy or cysto-ventriculostomy via a single burr hole. The follow-up periods ranged from six to 18 months. There was no mortality or morbidity except one case of intracisternal bleeding during endoscopic procedure. Symptoms were relieved in all seven patients. Follow-up imaging studies revealed a decrease in the size or disappearance of the cysts. The results support that the minimal fenestration procedure as possibly as preserving the internal environment is valuable for the management of ACs.  (+info)

Neurodevelopmental outcome after antenatal diagnosis of posterior fossa abnormalities. (7/167)

Posterior fossa abnormalities are sonographically diagnosable in the fetus. Anomalies of this region include Dandy-Walker malformation, enlarged cisterna magna, and arachnoid cyst. Despite prenatal diagnosis, the uncertainties related to natural history and neurodevelopmental outcome in survivors make patient counseling difficult. The purposes of this study were to determine the accuracy of prenatal diagnosis of these lesions and elucidate long-term neurodevelopmental outcome in survivors in prenatally diagnosed posterior fossa abnormalities. Fifteen cases of posterior fossa abnormalities were reviewed. Antenatal diagnoses of Dandy-Walker malformation was made in 13 of these cases, arachnoid cyst in one case, and enlarged cisterna magna in one case. Hydrocephalus was present in 66% of patients. The sonographic diagnosis was concordant with the pathologic or neonatal radiologic diagnosis in 13 of 15 cases. Seven fetuses (47%) exhibited additional cranial or extracranial anomalies. A karyotypic abnormality (trisomy 18) was found in one of 15 cases of posterior fossa abnormalities. Neurodevelopmental delay was present in 80% of survivors with follow-up study to 4 years of age. Prenatal diagnosis of posterior fossa abnormalities is highly accurate, yet the differential diagnosis can be challenging. Cognitive and psychomotor developmental delays remain commonplace despite early diagnosis and treatment. The approach with families in cases of prenatal diagnosis of posterior fossa abnormalities should include a search for additional central nervous system and extra-central nervous system anomalies in the fetus and counseling of parents regarding potential adverse outcome for survivors.  (+info)

Dandy-Walker syndrome successfully treated with cystoperitoneal shunting--case report. (8/167)

A neonate presented with Dandy-Walker syndrome manifesting as a large posterior cranial fossa cyst, aplasia of the lower cerebellar vermis, and elevation of the confluence of the sinuses but without hydrocephalus. A cystoperitoneal shunt was placed at one month after birth. The cyst diminished in size, and marked development of the cerebellar hemispheres and descent of the confluence of sinuses were observed, but not vermis development. The primary pathology of Dandy-Walker syndrome is posterior cranial fossa cyst formation due to passage obstruction in the fourth ventricle exit area and aplasia of the lower cerebellar vermis. The first choice of treatment in patients with Dandy-Walker syndrome in whom the cerebral aqueduct is open is cystoperitoneal shunt surgery, regardless of the presence or absence of hydrocephalus.  (+info)

Extradural arachnoid cysts in the spine are relatively uncommon causes of spinal cord compression in the pediatric population that are thought to arise from congenital defects in the dura mater. Most reports describe such cysts communicating with the intrathecal subarachnoid space through a small defect in the dura. The authors describe the case of a child who presented with spinal cord compression caused by a large spinal extradural arachnoid cyst that did not communicate with the intradural subarachnoid space. An 11-year-old girl presented with urinary urgency, progressive lower-extremity weakness, myelopathy, and severe gait ataxia. Magnetic resonance imaging of the spine demonstrated a large extradural arachnoid cyst extending from T-8 to T-12. The patient underwent a thoracic laminoplasty for en bloc resection of the spinal extradural arachnoid cyst. Intraoperatively, the dura was intact and there was no evidence of communication into the intradural subarachnoid space. Postoperatively, the

There is no Class I Evidence to guide how these should be treated. We suggest clinical decision-making framework as to how to treat IACs based on our understanding of the natural history, risks/benefits of treatments, and outcomes in the ...
Arachnoid cysts are congenital benign fluid collections within the arachnoid membrane-one of the 3 membranous layers that cover the brain and the spinal cord. The cyst is filled with a fluid similar to cerebrospinal fluid (CSF).. Arachnoid cysts may occur either in the brain or along the spinal cord. Most cases present during infancy; however onset of symptoms may be delayed until adolescence when the cyst has enlarged. Intracranial arachnoid cysts are reported to account for about 1% of all intracranial space-occupying lesions. This percentage, however, has probably been underestimated as with the advent of modern imaging techniques intracranial arachnoid cysts have become more frequently detected or diagnosed.. According to their size and location arachnoid cysts may not produce any symptoms and are only discovered incidentally on MRIs of the brain performed for a variety of reasons, or they may enlarge and become symptomatic by exerting pressure on the surrounding brain or by interfering with ...
Arachnoid cysts are benign, fluid-filled sacs in the brain or spine. The three most common surgical treatments for arachnoid cysts in the brain are craniotomy fenestration, endoscopic cyst fenestration or shunt placement. The nonsurgical treatment is close observation of the cyst.. Usually, arachnoid cysts develop between the surface of the brain and the skull base, or on the arachnoid membrane, one of the three membranes that cover the brain and the spinal cord. Less often, they arise in the spine.. For information on spinal arachnoid cysts, please click here.. Arachnoid cysts are the most common type of intracranial cyst and are typically found in the temporal fossa, the posterior fossa and the suprasellar region.. Untreated arachnoid cysts may cause permanent, severe neurological damage due to expansion of the cyst, hydrocephalus or hemorrhage. With treatment, most individuals with arachnoid cysts have a good prognosis.. ...
A collection of disease information resources and questions answered by our Genetic and Rare Diseases Information Specialists for Spinal intradural arachnoid cysts
Arachnoid cysts are intra-arachnoid collections of cerebrospinal fluid. Arachnoid cysts of the posterior fossa are rare lesions that are considered to be mostly congenital in origin. Arachnoid cysts of the posterior cranial fossa may manifest themselves in several different ways. When they are symptomatic, headache, gait disturbance, nausea, vomiting, focal neurologic signs, dizziness, and seizures are most common in the patients with increased intracranial pressure. Increased intracranial pressure is caused by the ball-valve mechanism of the cysts membrane that communicates with subarachnoid space or arachnoid cells and contains specialized membranes and enzymes, which have secretory activity. A postsurgical arachnoid cyst in the posterior cranial fossa has doubled and slitlike arachnoid membrane that supports our knowledge about the underlining mechanism is reported. ...

Arachnoid cysts (ACs), particularly suprasellar cysts, cause a wide spectrum of endocrine disorders. Herein, we report two patients diagnosed with an extensive AC in the middle cranial fossa while being investigated for etiologies of precocious puberty and short stature. One of them required surgery due to his pubertal disorders associated with compression effects of cyst. After surgery, his puberty progression was regressed within one year. On the other hand, surgery was not planned for the second patient considering of his cranial imaging findings and the extremely low incidence of growth hormone (GH) deficiency caused by middle fossa AC (MFAC). We started treatment with recombinant human GH and no complication was found during treatment follow-up. Endocrine disorders associated with MFACs are extremely rare. By presenting with these two cases, we aimed to remain our fellow physcians that ACs can be possibly cause of endocrine disorders. Clinicians should be careful evaluating endocrine ...

Four children, ages 12 to 15 years, with intracranial arachnoid cysts complicated by increased intracranial pressure are reported from Childrens Hospital of Philadelphia, PA. They presented with recent onset or increasing headaches, exacerbated by the supine position. Visual acuity was normal. Optic discs were swollen. Opening pressures at LP were 37 to 54 cm H20. All failed to respond to conservative medical therapies, but symptoms improved after a surgical shunting procedure. The arachnoid cyst was in the left middle temporal fossa and was complicated by a Chiari I malformation in 3 patients; one patient had hydrocephalus diagnosed at 18 months and a posterior fossa cyst. Three patients were previously treated with a cystoperitoneal shunt before age 2 and required shunt revision. [1]. COMMENT. Usually benign, arachnoid cysts are rarely complicated by increased intracranial pressure that may require a surgical shunt procedure.

A variety of cystic lesions may develop in spinal canal. These cysts can be divided into intramedullary, intradural, extradural, cervical, thoracic, lumbar, and sacral cysts according to anatomical presentation, as well as arachnoid, meningeal, perineural, juxtafacet, discal, neurenteric cysts, and cyst-like lesions according to different etiologies. Mechanisms of initiation and growth vary for different cysts, such as congenital, trauma, bleeding, inflammatory, instability, hydrostatic pressure, osmosis of water, secretion of cyst wall, and one-way-valve effect, etc. Up to now, many treatment methods are available for these different spinal canal cysts. One operation method can be applied in cysts with different types. On the other hand, several operation methods may be utilized in one type of cyst according to the difference of location or style. However, same principle should be obeyed in surgical treatment despite of difference among spinal canal cysts, given open surgery is melely for symptomatic

Progressive ataxia and quadriparesis in two shih tzu littermates was found to be caused by almost identical, cranial cervical, spinal arachnoid cysts. The cysts were treated surgically by dural marsupialisation via a dorsal laminectomy. One pup recovered uneventfully and remains clinically normal more than a year after surgery. The second pup made a slow and incomplete recovery before the signs worsened, necessitating euthanasia. Postmortem examination showed no evidence of the re-formation of the cyst.. ...
Spinal arachnoid cysts are known to be relatively uncommon lesions that may be either intra- or extradural. Intradural spinal arachnoid cysts are even less common. These cysts are usually asymptomatic but may produce symptoms by compressing the spinal cord or nerve roots suddenly or progressively. Arachnoid cysts represent approximately 1% of all intracranial masses and are relatively uncommon at the level of the spinal canal. In fact, they are usually located in the thoracic region (80%), as compared with 15% in the cervical spine and 5% in the lumbar spine. The problem presents in all age groups, but up to 75% are discovered in children. There is a 3:1 predominance in males. They may appear as a single or as multiple cysts. Its etiology is unclear; however, most spinal intradural cysts are thought to be congenital. Back pain is the most common onset symptom, followed by sensory changes, urinary dysfunction, and weakness. Changes in posture often cause variation of symptoms. CT myelography and ...
Arachnoid cysts are a common type of cyst which can affect the brain or spinal cord. Many arachnoid cysts remain constant in size.
I - INTRODUCTION Described for the first time in 1831 by BRIGHT, the arachnoid cyst is an arachnoid formation whose walls are purely arachnoid and does not differentiate itself from the neighboring arachnoid tissue. It can develop wherever there is arachnoid but it tends to localize in the peri-cephalic arachnoid
An arachnoid cyst is a fluid-filled sac of the brain or spinal cord. It forms between the brain or spinal cord and the arachnoid membrane. An arachnoid cyst contains cerebrospinal fluid (CSF). These cysts appear most often in children, but they may also occur in adults.

Arachnoid Cyst. Arachnoid cysts are CSF-containing cysts that are found in the middle fossa, posterior fossa, suprasellar cistern, or near the vertex. They are benign but slowly grow as they accumulate fluid, compressing normal brain structures. Remodeling of the adjacent skull is an important clue for a benign expansile process. Arachnoid cysts are smoothly marginated and homogeneous. They are not calcified and do not enhance. The multiplanar capability of MR is particularly helpful in establishing the exact location, and the diagnosis is supported by the cyst fluid being isointense with CSF on all pulse sequences. ...

The prevalence of arachnoid cysts in children is 1-3%. They are more frequent in boys. They can be located intracranially or in the spine. Intracranial cysts are classified as supratentorial, infratentorial, and supra-infratentorial (tentorial notch). Supratentorial are divided into middle cranial fossa, convexity, inter-hemisferic, sellar region, and intraventricular. Infratentorial are classified into supracerebellar, infracerebellar, hemispheric, clivus, and cerebellopontine angle. Finally spinal arachnoid cysts are classified taking into account whether they are extra- or intradural, and nerve root involvement ...
Visual impairment Almost all Arachnoid Cysts occur in relation to an arachnoid cistern. The most common locations are the middle cranial fossa (near the temporal lobe) and suprasellar (near the third ventricle). However, cysts may be found anywhere within the intracranial compartment, including the posterior cranial fossa.. Routine evaluation with CT or MRI scan is usually satisfactory. CT scans usually show a smooth bordered cystic mass composed of a density similar to cerebrospinal fluid. There is no enhancement with contrast administration. Expansion of the nearby bone by remodeling is usually seen, confirming their chronic nature. TREATMENT. Arachnoid cysts that do not cause significant mass effect or symptoms, regardless of their size and location, generally do not require treatment. If there is significant or severe mass effect on surrounding structures, or if there are symptoms, then surgical treatment is recommended. The following table summarizes the treatment options:. ...

Although hearing loss in newborns and infants is predominantly due to malformations and infections, there are other situations which may compromise hearing quality in later stages, including posterior-fossa arachnoid cysts (ACs). We report the case of an 8-year-old girl who presented with hearing loss linked to a pontocerebellar-angle AC which had been diagnosed and treated when she was 14 months old. The pathophysiology of this late AC complication is discussed. This case reminds us that a close follow-up with audiologic monitoring and/or brain stem auditory evoked response is necessary in children with posterior-fossa AC because modern neuroradiological imaging methods do not inform about cerebral and nerve functions, although they provide excellent morphological details of ACs and have improved the ease and accuracy of their early diagnosis. Therefore, surgery should be performed before complete hearing loss occurs; however, in hearing-impaired patients, it remains unclear which surgical treatment is

The initial MRI examination revealed a large-sized left temporal arachnoid cyst communicating with the left frontotemporal-parietal subdural hygroma with significant mass effects and midline shift to the right side. The differentiation between the arachnoid cyst and subdural hygroma can be based on the presence of the cortical veins sign, where the cortical veins can be seen traversing or superficial to the arachnoid cyst, but will always be deep to the subdural collection being compressed against the cortical brain surface ...

Y1 - 2016/1/1. N2 - Precocious puberty still remains an elusive diagnosis in the majority of patients. Infrequently, lesions of the central nervous system are associated with sexual precocity. Depending on their location, these cysts may affect many systems, however, there is little information concerning their involvement in endocrinological disorders. We report a case of a sylvian cistern arachnoid cyst presenting with precocious puberty in a 3-year-old girl. The child recovered following a cystoperitoneal shunt. The mass effect of the arachnoid cyst upon the hypothalamus was, at least in part, responsible for the development of precocious puberty. To the best of our knowledge, this is the 1st case of a sylvian cistern arachnoid cyst presenting with precocious puberty. The role of surgical ...

Hamzeh et al (2016) reported a family with two brothers affected with Chudley McCullough Syndrome. The two children were born to healthy consanguineous Yemeni parents. Both had bilateral severe sensorineural hearing loss and had cochlear implants placed in their right ears. Both had moderate speech delay and mild developmental delay. They had hyperextensible elbow and knee joints. Brain CT in the older brother revealed posterior third ventricular cystic lesion, suggestive of an arachnoid cyst, along with partial agenesis of the corpus callosum. In the younger brother, CT brain showed the presence of a large posterior third ventricular arachnoid cyst extending to the left of the midline, compressing the left hemisphere and lateral ventricles. Partial agenesis of the corpus callosum was also seen. There was a positive family history of hearing loss and speech delay in the family, with the two of the parents maternal cousins being affected.

The authors conducted a retrospective study of 107 patients treated for syringomyelia associated with arachnoid scarring between 1976 and 1995 at the Departments of Neurosurgery at the Nordstadt Hospital in Hannover, Germany, and the University of California in Los Angeles, California. Twenty-nine patients have not been surgically treated to date because of their stable neurological status. Seventy-eight patients with progressive neurological deficits underwent a total of 121 surgical procedures and were followed for a mean period of 32 (±37) months. All patients demonstrated arachnoid scarring at a level close to the syrinx. In 52 patients the arachnoid scarring was related to spinal trauma, whereas 55 had no history of trauma and developed arachnoid scarring as a result of an inflammatory reaction. Of these, 15 patients had undergone intradural surgery, eight had suffered from spinal meningitis, three had undergone peridural anesthesia, and one each presented with a history of osteomyelitis, ...
MR studies in eight patients with extraaxial arachnoid cysts in the middle cranial fossa were reviewed in order to identify any associated structural defect in the ipsilateral temporal lobe. The study was prompted by the original theory that agenesis of the temporal lobe is the primary factor in the development of these cysts. Authors of subsequent studies proposed that the cysts are a consequence of embryological malformation of the meninges only and that the adjacent temporal lobe is compressed. Our findings suggest that middle cranial fossa cysts are associated with temporal lobe hypogenesis, and also that compression of the temporal lobe is an infrequent accompaniment. ...

Everything that has happened to me I later read to be quite rare conditions starting with my initial injury, a subdural hematoma in my spinal cord, very, very rare, probably caused by an arteriovenous malformation also rare. I then had an operation for an arachnoid cyst which formed at the initial lesion site, quite rare, and then followed up by syringomyelia which is like a fluid filled tube in the spinal cord which goes upwards, thus causing damage above my injury level. For me this meant a loss of sensation in my back and some pain in my upper right arm. Syringomyelia, also rare. Ive had so many rare things that I sometimes joke to myself that I ought to start buying lottery tickets. ...
Arachnoid cysts may or may not communicate with the cerebrospinal fluid pathways. Patterns of communication were studied in six patients, using metrizamide computed tomography (CT) cisternography, ventriculography, and cystography. Two types of cysts were found: one with free communication with the cerebrospinal fluid pathways and one with restricted communication. This information can be useful in the surgical management of the cysts. When the cysts freely communicate wih the ventricles, ventricular shunting is the appropriate therapy, whereas when the cysts are noncommunicating, direct shunting of the cyst is indicated. ...

Magnetic Resonance Imaging (MRI) allows the best visualization of soft tissue lesions, and is especially useful for diagnosing spinal cord lesions, such as IVDD, cancer, syringomyelia, and arachnoid cysts. MRI is non-invasive, but does require significant time to perform, and in general is less readily available to veterinary patients. Because of the time required, scanning of a large area (such as the thoracolumbar spine) in a large dog can be problematic. MRI is generally reserved for cases where CT/myelogram is inconclusive or for suspected intramedullary spinal cord tumors, lumbosacral disease, brachial plexus neoplasia or primary brain abnormalities.. Treatment. The decision to treat intervertebral disk disease medically or surgically depends on many factors, including speed of onset and progression of the disease, stage of the disease, response to medication, proximity of an experienced surgeon, and financial ability of the owner.

Dublins High Court have settled a claim for compensation made on the behalf of a child who had a delayed diagnosis of hydrocephalus.. On the 17th January 2008, Joe Keegan-Grant was delivered at the Mount Carmel Hospital in Dublin. He was born via an emergency Caesarean Section as a scan had shown that he had an arachnoid cyst at the base of his brain. The Caesarean was necessary to prevent pressure being applied to Joes head during delivery. After his discharge from hospital, Joe was regularly examined by Dr Vladka Vilimkova, a paediatrician, and a public health nurse. However, Joes mother - Patricia - has alleged that at no point during the examinations was the circumference of Joes head recorded. She also alleges that the professionals never exchanged measurements they had made. As a result of this lack of communication, there was a delay in realising that Joes head was expanding at a faster rate than expected. When the family moved house, and as such changed GP, their new doctor ...
Bryleigh had her CT scan Friday. They canceled the MRI of her spine that was suppose to be done. The insurance would not cover it for some reason. But if Dr. Price feels she needs one then we will have it done later on. She did really good for the CT. They put her to sleep for like 15 minutes. Afterwards we met with Dr. Price to go over the findings. She said that everything looked good with the shunt. Her ventricles had gotten smaller, and her head size had not increased. However, she did see what she thought was a small arachnoid cyst. She said that normally these do not cause a problem, but it can. She is going to have an MRI in 6 months to see if it has grown, if it has, then we will have to discuss surgery :-(. Also, she said that Bryleighs hydro was not aqueductal stenosis. I had read of a procedure ETV that can be done sometimes with the aqudectual stenosis. So Bryleigh does not really fall into that category. But, her fourth ventricle is small so she could possibly still be a candidate. ...

By the time Id figured out how to get the Vort Skull from The Twins part of the temple, Id well and truly used up my hour. I therefore had no choice but to restart, get a new item, and go wherever it led me. The next item I got was the rope, which would apparently be useful in the room titled De Profundis. As usual, I was immediately transported to that room, where I was met by a rather horrific beast in a pool of acid. I had to click the left mouse button to continue and as soon as I did, the beast sank beneath the deadly liquid, leaving me to ponder how I was going to reach the doorway on the other side of it. Gauss hint was hole don (hold on), but I could see nothing to hold onto. I sensibly saved my game, which was just as well, as even clicking on the door made the platform I was standing on sink a little bit into the acid. A vertical column did come down from the ceiling though, which looked like a perfect thing to hold onto ...
