Type I features similar, but less severe malformations and is without an associated meningomyelocele. Type III has the features of type II with an additional herniation of the entire cerebellum through the bony defect involving the foramen magnum, forming an ENCEPHALOCELE. Type IV is a form a cerebellar hypoplasia. Clinical manifestations of types I-III include TORTICOLLIS; opisthotonus; HEADACHE; VERTIGO; VOCAL CORD PARALYSIS; APNEA; NYSTAGMUS, CONGENITAL; swallowing difficulties; and ATAXIA.

Sphenoid bone consists of a median body and three pairs of processes resembling a bat with spread wings. The body is hollowed out in its inferior to form two large cavities (SPHENOID SINUS).Petrous Bone: The dense rock-like part of temporal bone that contains the INNER EAR. Petrous bone is located at the base of the skull. Sometimes it is combined with the MASTOID PROCESS and called petromastoid part of temporal bone.Mucocele: A retention cyst of the salivary gland, lacrimal sac, paranasal sinuses, appendix, or gallbladder. (Stedman, 26th ed)Mastoid: The posterior part of the temporal bone. It is a projection of the petrous bone.Neurilemmoma: A neoplasm that arises from SCHWANN CELLS of the cranial, peripheral, and autonomic nerves. Clinically, these tumors may present as a cranial neuropathy, abdominal or soft tissue mass, intracranial lesion, or with spinal cord compression. Histologically, these tumors are encapsulated, highly vascular, and composed of a homogenous pattern of biphasic fusiform-shaped cells that may have a palisaded appearance. (From DeVita Jr et al., Cancer: Principles and Practice of Oncology, 5th ed, pp964-5)Tomography, X-Ray Computed: Tomography using x-ray transmission and a computer algorithm to reconstruct the image.Hematoma, Subdural: Accumulation of blood in the SUBDURAL SPACE between the DURA MATER and the arachnoidal layer of the MENINGES. This condition primarily occurs over the surface of a CEREBRAL HEMISPHERE, but may develop in the spinal canal (HEMATOMA, SUBDURAL, SPINAL). Subdural hematoma can be classified as the acute or the chronic form, with immediate or delayed symptom onset, respectively. Symptoms may include loss of consciousness, severe HEADACHE, and deteriorating mental status.Zygoma: Either of a pair of bones that form the prominent part of the CHEEK and contribute to the ORBIT on each side of the SKULL.Cerebral Veins: Veins draining the cerebrum.Infratentorial Neoplasms: Intracranial tumors originating in the region of the brain inferior to the tentorium cerebelli, which contains the cerebellum, fourth ventricle, cerebellopontine angle, brain stem, and related structures. Primary tumors of this region are more frequent in children, and may present with ATAXIA; CRANIAL NERVE DISEASES; vomiting; HEADACHE; HYDROCEPHALUS; or other signs of neurologic dysfunction. Relatively frequent histologic subtypes include TERATOMA; MEDULLOBLASTOMA; GLIOBLASTOMA; ASTROCYTOMA; EPENDYMOMA; CRANIOPHARYNGIOMA; and choroid plexus papilloma (PAPILLOMA, CHOROID PLEXUS).Chondromatosis, Synovial: Rare, benign, chronic, progressive metaplasia in which cartilage is formed in the synovial membranes of joints, tendon sheaths, or bursae. Some of the metaplastic foci can become detached producing loose bodies.

This condition may result from central or peripheral lesions. Damage to CNS motor pathways from the cerebral cortex to the facial nuclei in the pons leads to facial weakness that generally spares the forehead muscles. FACIAL NERVE DISEASES generally results in generalized hemifacial weakness. NEUROMUSCULAR JUNCTION DISEASES and MUSCULAR DISEASES may also cause facial paralysis or paresis.Meningeal Neoplasms: Benign and malignant neoplastic processes that arise from or secondarily involve the meningeal coverings of the brain and spinal cord.Magnetic Resonance Imaging: Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.Paranasal Sinus Neoplasms: Tumors or cancer of the PARANASAL SINUSES.Hematoma, Epidural, Cranial: Accumulation of blood in the EPIDURAL SPACE between the SKULL and the DURA MATER, often as a result of bleeding from the MENINGEAL ARTERIES associated with a temporal or parietal bone fracture. Epidural hematoma tends to expand rapidly, compressing the dura and underlying brain. Clinical features may include HEADACHE; VOMITING; HEMIPARESIS; and impaired mental function.Pterygopalatine Fossa: A small space in the skull between the MAXILLA and the SPHENOID BONE, medial to the pterygomaxillary fissure, and connecting to the NASAL CAVITY via the sphenopalatine foramen.Sphenoid Sinus: One of the paired air spaces located in the body of the SPHENOID BONE behind the ETHMOID BONE in the middle of the skull. Sphenoid sinus communicates with the posterosuperior part of NASAL CAVITY on the same side.Neurosurgical Procedures: Surgery performed on the nervous system or its parts.Arteriovenous Fistula: An abnormal direct communication between an artery and a vein without passing through the CAPILLARIES.

The locations and size of the shunts determine the degree of effects on the cardiovascular functions such as BLOOD PRESSURE and HEART RATE.Orbital Diseases: Diseases of the bony orbit and contents except the eyeball.Ear, Middle: The space and structures directly internal to the TYMPANIC MEMBRANE and external to the inner ear (LABYRINTH). Its major components include the AUDITORY OSSICLES and the EUSTACHIAN TUBE that connects the cavity of middle ear (tympanic cavity) to the upper part of the throat.Skull: The SKELETON of the HEAD including the FACIAL BONES and the bones enclosing the BRAIN.Cavernous Sinus: An irregularly shaped venous space in the dura mater at either side of the sphenoid bone.Orbital Neoplasms: Neoplasms of the bony orbit and contents except the eyeball.Cerebral Angiography: Radiography of the vascular system of the brain after injection of a contrast medium.Imaging, Three-Dimensional: The process of generating three-dimensional images by electronic, photographic, or other methods. For example, three-dimensional images can be generated by assembling multiple tomographic images with the aid of a computer, while photographic 3-D images (HOLOGRAPHY) can be made by exposing film to the interference pattern created when two laser light sources shine on an object.Dandy-Walker Syndrome: A congenital abnormality of the central nervous system marked by failure of the midline structures of the cerebellum to develop, dilation of the fourth ventricle, and upward displacement of the transverse sinuses, tentorium, and torcula. Clinical features include occipital bossing, progressive head enlargement, bulging of anterior fontanelle, papilledema, ataxia, gait disturbances, nystagmus, and intellectual compromise. (From Menkes, Textbook of Child Neurology, 5th ed, pp294-5)Cerebellar Neoplasms: Primary or metastatic neoplasms of the CEREBELLUM. Tumors in this location frequently present with ATAXIA or signs of INTRACRANIAL HYPERTENSION due to obstruction of the fourth ventricle. Common primary cerebellar tumors include fibrillary ASTROCYTOMA and cerebellar HEMANGIOBLASTOMA. The cerebellum is a relatively common site for tumor metastases from the lung, breast, and other distant organs. (From Okazaki & Scheithauer, Atlas of Neuropathology, 1988, p86 and p141)

The supraorbital keyhole approach with eyebrow incisions for treating lesions in the anterior fossa and sellar region. (1/28)

BACKGROUND: Keyhole surgery has developed since the 1990s as a less invasive therapeutic strategy for intracranial lesions, initially for the treatment of intracranial aneurysms. The purpose of this study was to describe and evaluate the results of surgical treatment of lesions in the anterior fossa and sellar region via a supraorbital keyhole approach using eyebrow incisions. METHODS: Between April 1994 and July 2003, 54 patients with lesions in the anterior fossa and sellar region were operated on via the supraorbital keyhole approach. The surgical results were studied retrospectively and compared with that of patients with lesions at the same locations but treated via a conventional subfrontal approach. RESULTS: No significant difference in curative effect was found between the conventional subfrontal approach and the supraorbital keyhole approach. However, the supraorbital approach required a much smaller skin incision, causing less surgical trauma, while achieving excellent surgical exposure and good recovery. CONCLUSION: The supraorbital keyhole approach using an eyebrow incision is safe, effective, and both suitable and convenient for treating lesions in the anterior fossa and sellar region, with almost no adverse consequences on the facial features of patients.  (+info)

Detection of enlarged cortical vein by magnetic resonance imaging contributes to early diagnosis and better outcome for patients with anterior cranial fossa dural arteriovenous fistula. (2/28)

Twelve patients (10 men, 2 women) with anterior cranial fossa dural arteriovenous fistula (AVF) were treated at our institute between January 1976 and March 2002. Intracranial hemorrhage was the presenting symptom in six patients. Magnetic resonance (MR) imaging findings identified abnormal cortical veins as flow voids in four of five patients. Angiography was the basis of the diagnosis in all patients. Surgery was the primary treatment in nine patients. The other three patients refused intervention and managed conservatively. Surgical morbidity was negligible and the treatment outcome was highly dependent on the clinical status at presentation. In contrast to the reported high incidence of intracranial hemorrhage in patients with dural AVF in the anterior cranial fossa, only half of our study population presented with hemorrhage. Enlarged cortical veins in the frontobasal area could be detected as flow voids on MR images. This finding contributed to the early diagnosis and treatment of patients treated at our institution for dural AVF in the anterior cranial fossa, and to the better outcomes we obtained in these patients.  (+info)

Craniofacial resection for cranial base malignancies involving the infratemporal fossa. (3/28)

OBJECTIVE: Cranial base malignancies involving the infratemporal fossa have been considered unresectable. Advanced operative techniques have made tumor resection feasible in an en bloc fashion with negative histological margins, but there are limited data regarding outcome analysis in patients who have undergone resection of malignant tumors in this area. METHODS: At Memorial Sloan-Kettering Cancer Center, 25 patients underwent anterolateral cranial base resections for tumors that involved the infratemporal fossa during a 7-year period. The most common tumors were sarcoma (n = 9), squamous cell carcinoma (n = 6), and adenoid cystic carcinoma (n = 3). The median size of the tumors was 6 cm, and 12 tumors involved the anterior cranial base and/or orbit. Tumor resections were divided into three types. Twelve patients underwent Type 1 dissection for tumors involving only the infratemporal fossa and maxillary sinus; 2 patients underwent Type 2 dissections involving the infratemporal fossa and anterior cranial base; and 11 patients underwent Type 3 dissection, which included the infratemporal fossa, anterior cranial base, and orbit. All patients required free flap reconstruction, 22 of which were rectus abdominis free flaps. RESULTS: Complications occurred in seven patients, including a single mortality resulting from a myocardial infarction. The 2-, 3-, and 5-year survival rates were 69, 63, and 56%, respectively. The relapse-free survival rates were 47% at 2 and 3 years and 41% at 5 years. Recurrences were local in nine patients and distant in four patients. CONCLUSION: Despite the extensive nature of many infratemporal fossa tumors, they can be resected with acceptable morbidity. Survival rates approach those of anterior cranial base malignancies without infratemporal fossa involvement.  (+info)

Anterior ethmoidal artery aneurysm and intracerebral hemorrhage. (4/28)

The association between the formation of intracranial aneurysms and situations of increased blood flow in certain areas of the brain is well accepted today. It has been seen in association with arteriovenous malformations of the brain, carotid occlusion, and Moyamoya disease. The occurrence of aneurysms in small arteries of the skull base, with the exception of the intracavernous carotid artery, however, is rare. We report a case of a 55-year-old woman who presented with an intracerebral hemorrhage caused by a ruptured anterior ethmoidal artery aneurysm. To the best of our knowledge, this is only the second case of documented intracranial bleeding from such a lesion.  (+info)

Venous aneurysm development associated with a dural arteriovenous fistula of the anterior cranial fossa with devastating hemorrhage--case report. (5/28)

A 67-year-old man presented with devastating intracranial hemorrhage (ICH) from an anterior cranial fossa dural arteriovenous fistula (DAVF). Four years earlier, digital subtraction angiography had disclosed a DAVF at the right anterior cranial fossa fed mainly by the ethmoidal branches of the bilateral sphenopalatine arteries and slightly by the ethmoidal arteries of the bilateral ophthalmic arteries, and drained primarily by the sphenoparietal and cavernous sinuses via two dilated cortical veins and slightly by the superior sagittal sinus via a frontal ascending vein. Three-dimensional computed tomography angiography revealed the development of a venous aneurysm on the main draining vein over a 4-year period, but no other changes. Venous aneurysm development may be part of the natural history of DAVF with cortical venous drainage and may contribute to the occurrence of ICH.  (+info)

Usefulness of T2*-weighted MR sequence for the diagnosis of subfrontal schwannoma. (6/28)

Subfrontal schwannomas are rare tumors that are usually diagnosed during surgery. They are often misdiagnosed as meningioma or esthesioneuroblastoma because of their similar clinical and radiological features. We report a case of schwannoma arising from the floor of the anterior cranial fossa that had radiological features similar to that of meningioma. However, T2*-weighted MR imaging revealed multiple foci of low signal intensities within the tumor related to microbleeds, which suggested a diagnosis of schwannoma that was confirmed by histopathology. This case report demonstrates the usefulness of T2*-weighted sequence in distinguishing meningioma from schwannoma, especially in cases where the tumor has an unusual location.  (+info)

Osteoma of anterior cranial fossa complicated by intracranial mucocele with emphasis on its radiological diagnosis. (7/28)

We present a 43-year-old female patient who had recurrent headache for one year. An intracranial bony lesion surrounded by a cyst in the anterior cranial fossa was found on imaging. Postoperative histological examination confirmed the diagnosis of osteoma and mucocele.  (+info)

Intracranial aspergilloma in immunocompetent patients successfully treated with radical surgical intervention and antifungal therapy: case series. (8/28)

INTRODUCTION: Aspergillosis of the central nervous system is an uncommon infection, mainly occurring in immunocompromised patients with a high mortality. Surgical excision of the intracranial lesion combined with oral voriconazole has been proposed to improve the outcome in immunocompromised patients. Itraconazole has been considered not to be effective because of poor penetration into the brain tissue. We report the long-term outcome of 3 cases of intracranial aspergilloma in immunocompetent patients who were successfully treated with radical surgery combined with oral itraconazole. MATERIALS AND METHODS: This is a retrospective study in which chronic invasive intracranial aspergilloma was successfully treated in 3 apparently immunocompetent patients and followed-up for more than 5 years. RESULTS: Near complete or radical surgical removal of this localised chronic invasive intracranial aspergilloma whenever possible is the definitive treatment. When combined with the oral antifungal drug itraconazole, the management regimen is effective in achieving near complete long-term cure of more than 5 years. Oral itraconazole 200 mg twice daily should be given for a prolonged period of at least 6 months. CONCLUSION: In chronic invasive intracranial aspergilloma in an immunocompetent patient, it was suggested that radical excision of the intracranial aspergilloma combined with oral antifungal drug belonging to triazole group that can be either itraconazole or voriconazole given for a period of 6 months was likely to improve the long-term outcome.  (+info)

Looking for online definition of anterior cranial fossa in the Medical Dictionary? anterior cranial fossa explanation free. What is anterior cranial fossa? Meaning of anterior cranial fossa medical term. What does anterior cranial fossa mean?
The posterior ethmoidal artery is an artery of the head which supplies the nasal septum. It is smaller than the anterior ethmoidal artery. Once branching from the ophthalmic artery, it passes between the upper border of the medial rectus muscle and superior oblique muscle to enter the posterior ethmoidal canal. It exits into the nasal cavity to supply posterior ethmoidal cells and nasal septum; here it anastomoses with the sphenopalatine artery. There is often a meningeal branch to the dura mater while it is still contained within the cranium. This artery supplies the posterior ethmoidal air sinuses, dura mater of the anterior cranial fossa, and the upper part of the nasal mucosa of the nasal septum.

The instructor will insert fingers between the frontal lobe and the floor of the anterior cranial fossa to gently raise the frontal lobe to display the olfactory bulb as it lies on the cribriform plate (842/N9). If possible, identify the olfactory tract extending posteriorly from the bulb to the inferior surface of the hemisphere. The bulbs can be teased away from the cribiform plate so that bulbs and tracts remain with the brain. Additional elevation of the two frontal lobes will display the optic nerves and chiasm (N101) in the midline about 2 ½ inches posterior to the crista galli. With a small pair of scissors the optic nerves are cut leaving the optic chiasm on the brain. (It is best to sever all cranial nerves with a scissors; pressure on them even with a sharp scalpel is likely to tear them from the brain). Immediately posterior to each optic nerve are the internal carotid arteries (893/N132). In the midline the very slender infundibulum (N100) (stalk of the hypophysis) is seen passing ...
Planum sphenoidale and tuberculum sella meningiomas arise from the floor of the anterior cranial fossa near the midline and present with visual disturbances due to compromise of the optic nerves and chiasm necessitating surgical removal in most cases. The traditional craniotomy and open surgical removal with decompression of the optic apparatus has been effectively used for many years.. A minimally invasive cranial approach via a supraorbital incision and bone opening is also reportedly used quite effectively to remove these tumors. Another option is the endoscopic endonasal approach (EEA) that has been increasingly used for this purpose over the past decade, and in experienced hands, has proven to be a safe and effective option as well. To date, the literature is limited primarily to small single institution, retrospective studies and meta-analyses comparing outcomes between the EEA and transcranial approaches. Here are a few seminal reviews.. In 2012, Komotar et al., published a meta-analysis ...
Andrei Makovik was a software designer and computer programmer from Minsk, Belarus. He moved to Ann Arbor with his family in 1994 and was employed in the Information Technology department at Cayman. In November 2004, when he was 37, it was discovered that he had a large, invasive tumor of the nasal sinuses eroding upward through the cribriform plate. He underwent a subcranial resection of undifferentiated high-grade cancer of the right nasal cavity and anterior cranial fossa in January 2005. He subsequently underwent chemotherapy with Cisplatin (40 mg/m², 6 weekly sessions) and radiation therapy (24 5-days-a-week sessions). He was symptomatically and radiographically free of disease until October of 2005, when several foci of recurrent tumor where found on MRI, mainly growing in the dura. A biopsy of one tumor from the right parietal dura was obtained by craniotomy on November 9, 2005. The 2.5 × 3 cm specimen was divided into 18 samples and distributed between University of Michigan Pathology, ...

The middle cranial fossa (latin: fossa cranii media) is a region of the internal cranial base between the anterior and posterior cranial fossae, it lies deeper and is wider than the anterior cranial fossa.
The middle fossa, deeper than the anterior cranial fossa, is narrow medially and widens laterally to the sides of the skull. It is separated from the posterior fossa by the clivus and the petrous crest.It is bounded in front by the posterior margins of the lesser wings of the sphenoid bone, the anterior clinoid processes, and the ridge forming the anterior margin of the chiasmatic groove; behind, by the superior angles of the petrous portions of the temporal bones and the dorsum sellæ; laterally by the temporal squamæ, sphenoidal angles of the parietals, and greater wings of the sphenoid. It is traversed by the squamosal, sphenoparietal, sphenosquamosal, and sphenopetrosal sutures. It houses the temporal lobes of the brain. ...
Cancer of the nasal acavity and paranasal sinuses is relatively rare, ocurs more often in men (2:1) and usually appears after 40 years, (except minor salivary gland origin, lymphoma, or esthesioneuroblastoma). Squamous cell carcinoma is the most common type, followed by adenocarcinoma. These tumors have a propensity to grow slowly, insidiously towards the anterior skull base and orbit. Imaging is essential since it allows a precise tumor mapping, a key element for therapeutic planning. CT allows to visualize the bony structures, particularly the internal orbital wall and cribriborm plate. MR permits to differentiate between the tumor, which most often is seen as a T2 weighted low signal intensity area, and inflammatory tissue which shows up bright. In addition it can displays meningeal and intracerebral involvement. MR information can help selecting the correct surgical approach, particularly a combined neurosurgical-ENT approach if the anterior cranial fossa has to be removed ...
What is the Cribriform Plate? In the human skull, Cribriform Plate is a significant part that separates the brain from the nasal cavity. It is like a honeycomb or sieve-like structure that is thin and narrow and has tiny perforations. This plate which is situated between the anterior cranial fossa and the nasal cavity

The word fontanel comes from the French fontaine for fountain. The medical term fontanel is a "soft spot" of the skull. The "soft spot" is soft precisely because the cartilage there has not yet hardened into bone between the skull bones. There are normally two fontanels, both in the midline of the skull, one (the anterior fontanel) well in front of the other (the posterior fontanel). ...

The blastema covers almost all of the lateral surface of the cartilaginous skull. A small part of the occipital cartilage, including the transverse process, part of the squama and occipital neural arch, part of the orbital wing of the sphenoid, and part of the lateral surface of the nasal capsule, are uncovered (figs. 9 and 15). Into the blastema covering the squamal cartilage, rather than into the cartilage itself, are inserted the various occipital muscles (figs. 14 and 15). The blastema covering the squama and the lateral surface of the otic capsule probably fases later with the perichondrium, but at this stage it seems to be continuous with the rest of the blastemal wall which later gives rise to membrane bones. It is in the sphenoidal and frontal regions that the blastema greatly predominates over the cartilage. All of the lateral wall of the middle cranial fossa consists of blastema and the greater part of the floor (as well as all of the lateral wall of the anterior fossa) is likewise ...

The Skull Base, upon which the Brains undersurface rests, has three main regions. The Anterior (front) Cranial Fossa is the region located above the eyes and includes structures such as: the Olfactory Bulbs, the Nasal Cavity, and Cranial Nerves (1 & 2 and sections of 3, 4 & 6) that control vision, as well as movement of the eyeballs. The Middle Cranial Fossa is the region containing the dense, boney Petrous Ridge, and houses the Internal Carotid Artery, along with sections of the Cranial Nerves (5 & 7) that control chewing and facial sensation. The Middle Cranial Fossa also contains the Cavernous Sinus, an extremely difficult structure from which to remove tumors. The Posterior (back) Cranial Fossa is where the Internal Auditory Canal (IAC) and the Cranial Nerves (7 & 8) responsible for hearing, facial expression and balance are located; the Jugular Vein also passes through this region. Of the 24 highly specialized Cranial Nerves, which control many vital functions of our head and neck, 18 ...

A newborns shoulders and hips are narrow, the abdomen protrudes slightly, and the arms and legs are relatively short. The average birth weight of a full-term newborn is approximately 7 ½ lbs.(3.2 kg), but is typically in the range of 5.5-10 pounds (2.7-4.6 kg). The average total body length is 14-20 inches (35.6-50.8 cm), although premature newborns may be much smaller. The Apgar score is a measure of a newborns transition from the uterus during the first minutes of life. A newborns head is very large in proportion to the rest of the body, and the cranium is enormous relative to his or her face. While the adult human skull is about 1/8 of the total body length, the newborns is about 1/4. At birth, many regions of the newborns skull have not yet been converted to bone, leaving "soft spots" known as fontanels. The two largest are the diamond-shaped anterior fontanel, located at the top front portion of the head, and the smaller triangular-shaped posterior fontanel, which lies at the back of ...

Traumatic dislocation of the mandibular condyle into the middle cranial fossa complicated by temporal lobe intracerebral hemorrhage: literature review and our case
This report is the first clinical description of the endoscopic extradural supraorbital approach to the temporal pole. Temporal pole exposure by craniotomy needs wide elevation of the temporal muscle and broad removal of the lateral bone of the middle cranial fossa, resulting in temporal muscle atrophy, disturbed mastication, and poor cosmetic results. Furthermore, the lateral trajectory from the frontotemporal craniotomy does not satisfactorily expose the temporal pole. In contrast, our previous anatomical studies regarding the endoscopic extradural supraorbital approach demonstrated excellent visualization of the middle cranial fossa and temporal pole through the supraorbital keyhole, and the approach eliminated temporal muscle elevation and craniotomy.15,18,19 Therefore, mastication discomfort was avoided even with temporal pole surgery. The trajectory from the anterior direction was optimal to visualize the temporal pole, and it minimized the corticotomy on the temporal pole. A dural ...

The skull is made up of many bones, 8 in the skull itself and 14 in the face area. They join together to form a solid, bony cavity that protects and supports the brain. The areas where the bones join together are called the sutures.. The bones are not joined together firmly at birth. This allows the head to change shape to help it pass through the birth canal. The sutures get minerals added to them over time and harden, firmly joining the skull bones together.. In an infant, the space where two sutures join forms a membrane-covered "soft spot" called a fontanelle (fontanel). The fontanelles allow for growth of the brain and skull during an infants first year.. There are normally several fontanelles on a newborns skull. They are located mainly at the top, back, and sides of the head. Like the sutures, fontanelles harden over time and become closed, solid bony areas.. ...
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. ...
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:. ...

When a person is surprised, their eyebrows are often raised. This typically happens as a part of opening the eyes wider, perhaps to see more clearly what is going on. The more the surprise. the higher the eyebrows are raised.. Raising the eyebrows asks for attention from others and can signal general emphasis. When as question is asked and the eyebrows are raised afterwards, this is a clear invitation to answer the question.. Opposite to the dominant lowering of eyebrows, raising eyebrows is may be a submissive move or indicate openness, as it lets the other person see your eyes (I am not looking where I should not!).. Raising a single eyebrow is something that only some people can do and can be a bit more wry in its meaning, for example asking Are you sure? when the other person appears to be talking with limited accuracy.. _____________________________________________________________ ...

Primary pigmented tumors of the CNS are unusual; they include melanotic schwannoma, meningeal melanocytoma, blue nevus of the CNS, and primary melanoma (3-6). Among these lesions, primary malignant melanoma of CNS is rare and accounts for about 1% of all melanomas. Primary malignant melanoma of the spinal cord is a very rare entity, occuring most often in the middle or lower thoracic cord (1-8). Among the 27 cases of CNS malignant melanoma that Hayward (1) reported, only four lesions were in the spinal cord. Hirschberg (9) first reported primary spinal cord melanoma in 1906. Since then, a few cases have been reported in the literature; these involve intra- or extramedullary, leptomeningeal, and extradural lesions (1-3, 5, 7, 8).. A malignant melanoma can occur in any organ in which melanin-containing cells are present. Two theories have been proposed for the origin of the rare cases of CNS melanoma. Primary melanoma in the CNS may originate from melanoblasts accompanying the pial sheaths of ...
posterior meningeal artery: branch of the ascending pharyngeal artery that supplies the dura mater of the posterior cranial fossa
Syringomyelia (SM) is a spinal cord disease that can cause neuropathic pain in dogs. The pathogenesis of SM secondary to Chiari-like malformation (CM) has been the focus of intense research in recent years. The gulf in our understanding of CM/SM in dogs relative to the analogous human condition has progressively narrowed. CM is primarily a disease of abnormal geometric morphometry affecting the caudal cranial fossa and the brain parenchyma contained within it. This review describes how advanced imaging techniques have revealed a series of morphometric abnormalities associated with CM/SM. The series is presented in a logical order to help describe the pathogenesis of CM and the subsequent formation of syringes, with particular reference to the concepts of craniospinal compliance and cerebrospinal fluid pulse pressure timing..

  • Postoperative cranial nerve deficiency was observed in 5 patients in the study group and in 13 patients in the control group. (biomedcentral.com)
  • We did not receive statistically significant data supporting the fact that intraoperative identification of cranial nerves using trigger electromyography reduces the incidence of postoperative complications in the form of cranial nerve deficits ( p = 0.56), but the odds ratio (0.6) suggests a less frequent occurrence of complications in the study group. (biomedcentral.com)
  • Thus, t-EMG allows to determine the location of a cranial nerve before coming into direct contact with it, and, therefore, reduces the risk of iatrogenic damage during all stages of tumor removal [ 21 ]. (biomedcentral.com)
  • Lower cranial nerve (IX-XII) palsy is a rare condition with numerous causes, usually non-traumatic. (biomedcentral.com)

Burdenko National Medical Research Center of Neurosurgery" of the Ministry of Health of the Russian Federation from 2013 to 2018. (biomedcentral.com)
  • Skull base meningiomas, which make up approximately 20 to 30% of meningiomas, are particularly prone to progression and recurrence given that these tumors are invested in and around the critical neurovascular structures of the cranial base making complete resection less feasible. (neupsykey.com)
