Composite pleomorphic xanthoastrocytoma-epithelioid glioneuronal tumor with BRAF V600E mutation - report of three cases.

We report three examples of a composite pleomorphic xanthoastrocytoma-epithelioid glioneuronal tumor (PXAEGT) occurring in an adolescent male and two young women. All were superficial and two were located in proximity to the optic nerves. Previously reported composite PXA-gangliogliomas (PXA-GG), have been considered "collision tumors" since little intermingling of the two elements has been present.

Intra-arterial nicardipine for the treatment of cerebral vasospasm in postpartum cerebral angiopathy: a case study and review of literature.

Introduction: Postpartum cerebral angiopathy is one of the many neurological complications seen during pregnancy and the postpartum period. Management of these patients consists of optimal blood pressure control, and general supportive critical care. We present a case of diffuse cerebral vasospasm, which improved with intra-arterial nicardipine.

Endoscopic techniques in resection of anterior skull base/paranasal sinus malignancies.
