The autapomorphic status of the Neanderthal suprainiac fossa was recently confirmed. Based on the results, it is mslamed that the Homo sapiens non-supranuchal fossa and Neanderthal suprainiac fossa are convergent traits. Considering the signal changes, high signal on T2-weighted T2-W sequences is seen from 25 WG in the posterior part of the brain stem tegmentum and ascending sensory tracts related to myelination.

Two weeks earlier, the patient suffered pain necessitating hospital admission, magnetic resonance imaging revealed a soft tissue mass in the right infratemporal fossa.

First, the variation in the expression of the fossa above inion in the crania of recent Homo sapiens from European, African, and Australian samples was examined, and the degree of structural similarity between these depressions and the Neanderthal suprainiac fossa was assessed.

Two of these patients had tinnitus and vertigo, and three had hearing loss. Eighteen rats Wistar were divided into three groups of six animals each according to the time of evaluation 15, 30 and 60 days. Traumatic posterior fossa epidural hematoma. The aim of this study is to evaluate prospectively the presence of endometriosis in the peritoneum of the ovarian fossa of patients affected by endometriomas and its correlation with the adhesion between this peritoneum and endometrioma.

Computed tomography demonstrated evidence of integration of the bone graft in eight cases between 4 and 9 months after surgery.


We evaluated the technical aspects of the supra-orbital keyhole approach considering the indications, limitations, and complications of this approach to treat anterior cranial fossa and parasellar meningiomas. A multivariable analysis of Covariance model will be used, with the assessment of the time by group interaction, using age as covariate.

Imaging descriptions of posterior fossa ependymoma in children have focused on magnetic resonance imaging MRI signal and local anatomic relationships with imaging location only recently used to classify these neoplasms. After the time of evaluation, the animals were killed, when the bone was histological studied and classified according to the type of tissue found: Although rare, it should be considered in the differential diagnosis of expansive lesions in the pterygopalatine fossaincluding schwannoma, angiofibroma, esthesioneuroblastoma, osteochondroma, cholesterol granuloma, hemangioma, lymphoma, and osteoma.

CT revealed a unilateral biconvex hematoma in two cases, and a bilateral hematoma with supratentorial extension in the third. The results of the interobserver agreement analysis regarding tumor invasion and extension to the infratemporal fossacavernous sinus, sphenoid sinus and medium cranial fossa were excellent.

Retrospective case series review. Four patients had a defect of the posterior semicircular canal. Herniography frequently reveals clinically undetected groin hernia.

Preauricular infratemporal fossa approach for advanced malignant parotid tumors. Posterior fossa extradural hematomas PFEDHs are apejandro as compared to supratentorial EDH and these patients can deteriorate very rapidly due to compression over brainstem.

Four patients with preoperative visual function defect had a complete recovery, whereas 3 patients experienced a transient worsening of vision, fully recovered within few days.

This study compared radiographic and CT evaluation with gross evaluation of the intercondylar fossa. For comparison and demonstration of topographic relationships, 58 casts of unselected radiograhed temporal bone specimens with high jugular fossae or diverticula were investigated. Review clinical experience with temporal fossa hemangiopericytomas HPCs.

In one of the latter the hearing loss was most marked in the supine position.

Here we present a case of schwannoma of the facial nerve at the middle cranial fossa that was misdiagnosed previously at a local hospital and then cured in our hospital. Nine patients underwent metrizamide cisternography of the posterior fossa. The inner part of cochlear implant is inserted into inner ear during surgery through mastoid and mlamed ear.


In the postoperative phase, ETV can be used in case of persisting hydrocephalus, both in patients who underwent only the excision of the tumor and in those whose preoperative ETV failed as a poorque of intraventricular bleeding with secondary closure of the stoma redoETV. Large intradiploic growing skull fracture of the posterior fossa. DWI alone can differentiate different pediatric posterior fossa brain tumors.

Pseudotumors, alejandroo masses and developmental cysts may also occur in the lacrimal fossa. Angiography showed a venous angioma in the left cerebellum which drained into the petrosal vein. This case is unique, and we believe that the presence of this variant in young children may be important and melaed not merely an anatomical curiosity.

Non-traumatic ones have been reported in patients who had idiopathic thrombocytopenic purpura or those who had been receiving anticoagulant therapy. Fracture of geniculate fossa of facial nerve canal was found in the operation in 30 patients, while the fracture was detected in CT in 18 patients. As a secondary outcome measure, evidence of integration of the split calvarial bone graft with the adjacent skull base was assessed.

Patient management, timing of radiological investigations and operations, and outcome were recorded prospectively. The age of presentation ranged from 31 to 62 years, and duration of follow-up ranged from 8 to months. The present study aims to introduce a sandwich closure of the dura in posterior fossa surgery, which reduces significantly the number of CSF leaks 3. The authors review the criteria for patient selection and the results of ETV performed in case of hydrocephalus secondary to a posterior fossa tumor.

A curvilinear draining vein was demonstrated by the enhanced CT.
