BACKGROUND We report the clinical, radiological, and surgical findings of patients with posterior fossa meningiomas surgically treated at our institution over the last 6 years. METHODS We reviewed 161 consecutive cases of posterior fossa meningiomas operated on between April 1993 and April 1999 at The George Washington University Medical Center. RESULTS(More)
OBJECTIVE To analyze long-term results and to determine prognostic factors on seizure outcome in a series of patients with temporal lobe epilepsy (TLE) who underwent anteromedial temporal lobectomy (AMTL). MATERIALS AND METHODS From 1995 to 1998 forty-two patients suffering from non-lesional TLE underwent tailored AMTL at our Institution. We(More)
OBJECT Intracranial intradural chordomas are extremely rare lesions, and only a few cases have been reported in the neurosurgical literature. The authors performed a retrospective analysis of cases treated at their institutions. They present an illustrative surgical scenario and discuss the published literature, pathogenesis, and histopathological features(More)
The chordoid variant of meningioma is a histological subtype which carries with it a more aggressive clinical course and a propensity for recurrence. Similar to other meningioma subtypes, this lesion is encountered typically in the supratentorial compartment, often along the cerebral convexities. The chordoid meningioma subtype is found primarily in the(More)
Encephaloceles are pathological herniations of brain parenchyma through congenital or acquired osseus-dural defects of the skull base or cranial vault. Although encephaloceles are known as rare conditions, several surgical reports and clinical series focusing on spontaneous encephaloceles of the temporal lobe may be found in the otological, maxillofacial,(More)
BACKGROUND Cranial nerve hemangioblastomas are exceedingly rare lesions. We review available literature and present the first surgical report on a solid hemangioblastoma arising from the trigeminal nerve and involving the Meckel cave that was successfully treated with selective embolization and successive surgical resection. CASE DESCRIPTION A 54-year-old(More)
Sinus mucoceles are benign, slowly enlarging, mucous-secreting, cystic lesions whose expansile growth may lead to compressive neuropathies. We present the case of a 70-year-old woman with a long-standing history of headaches and progressive ocular neuropathy who underwent an endoscopic resection of a large sphenoid sinus mucocele resulting in immediate(More)
OBJECTIVE We describe a variant of the interhemispheric translaminaterminalis approach for the resection of large suprasellar craniopharyngiomas. The approach is a translaminaterminalis route performed below and above the anterior communicating artery (ACoA). A cadaveric microanatomic study was conducted to describe the surgical technique. METHODS Four(More)
BACKGROUND AND STUDY OBJECTIVE Several surgical approaches have been previously reported for the treatment of olfactory groove meningiomas (OGM).The trans-frontal-sinus subcranial approach (TFSSA) for the removal of large OGMs is described, comparing it with other reported approaches in terms of advantages and drawbacks. MATERIAL AND METHODS The TFSSA was(More)
Giant cell glioblastoma multiforme (gcGBM) is an unusual subtype of high-grade glioma (grade IV, World Health Organization classification). We report a patient with a rare acute tetraplegia, followed by lethal cardiac arrest, who had undergone a prior resection of a supratentorial gcGBM. Neuroradiological workup revealed a large, high cervical compressive(More)
