Intra-cranial melanomas are commonly metastatic from primary melanoma elsewhere in the body. The primary occurrence of a melanoma in the brain parenchyma is rare. We report a case of 38 year aged woman who presented with deviation of left eye and headache. On imaging, a space occupying lesion was found in the left Cerebello-pontine angle and a preoperative diagnosis of meningioma was made. She ...

background and importance: our learning curve during two decades of neurosurgical practice has been changed from an abstractive to a more meaningful and conductive state. in cases of fifth nerve neurinoma, pre-operative anatomopathologic diagnosis could lead us to a pre-planned program during and after the surgery to get the safe surgical result. case presentation: representation of two complex...

background & importance: primary hemifacial spasm is usually caused by microvascular compression of the facial nerve at its root exit zone at brainstem without any space-occupying pathology. secondary or so-called symptomatic hemifacial spasm has an additional underlying pathology e.g. tumors leading to the microvascular compression. we review and discuss the pathophysiology and the literature ...

medulloblastoma is quite uncommon in the adult population and even rarer in extra-axial site in cerebello- pontine (cp) angle. in this report, a 23-year-old male patient with a two month history of deafness, nausea, vomiting and ataxia is presented. clinical and radiological findings demonstrated a heterogeneously enhanced extra-axial lesion in the right cp angle. total excision was performed a...

Cerebellopontine angle (CPA) tumors are the most common neoplasms in posterior fossa, accounting for 5-10% of intracranial tumors. Most CPA benign, with over 85% being vestibular schwannoma (acoustic neuromas). The preferred treatment symptomatic has been surgical excision. Craniotomy resections lateral position gave better field exposure, but also posed increased risk ventilation-perfusion mis...
