[Hemangiopericytoma of the meninges]

A 44-year-old farmer complained blurred vision and disturbance of recent memory. During his driving car traffic accident happened due to his right homonymous hemianopsia. On the 1st admission, neurological examination revealed choked disc(1 D.), hemianopsia, memory disturbance, dyscalculia, dyslexia and dysgraphia. The angiograms showed feeding arteries from left middle cerebral artery and posterior cerebral artery. Tumor vessels looked like cork-screw in the arterial phase and homogeneous tumor shadow was depicted in late venous phase. Contrast enhancement CT scan revealed a nodular homogeneous high dense lesion on the occipital region. Hemorrhage during every craniotomy was too much to remove and at last metastasized to left II rib and right VIII rib and right radius. Their histological examination reveals numerous endothelial-lined vascular channels and atypia of tumor cells with mitoses. Silver impregnation demonstrates networks of reticulum fibers surrounding the capillaries and tumor cells. Hemangiopericytoma in meninges forms entity and our case reports the WHO classification. Total removal should have to be done once for all by means of LASER (light amplification by stimulated emission of radiation).
