[A case of tentorial cavernous angioma].
A case of tentorial cavernous angioma is reported. A 61-year-old woman was admitted because of left auditory disturbance and left hemifacial spasm. CT scan and angiography, MRI revealed a dumb-bell typed tumor extended above and below the left tentorium cerebelli. Under the preoperative diagnosis of tentorial meningioma, a craniotomy was performed and the tumor was removed totally with minimal bleeding by left subtemporal approach. The tumor was well capsulated and spongy, attached to the tentorium cerebelli. Histologically, the tumor had many various vascular cavities with the wall lined with a single layer of endothelial cell, had neither glial cell nor meningeal cells. Some of cavities were thrombosed. Pathological diagnosis was a cavernous angioma. We discussed the characters of this rare tumor with a review of 4 cases.
