Cavernous sinus内より発生し，高プロラクチン血症を呈した中頭蓋窩のCavernous angiomaの1例

A Case of Cavemous Angioma of the Middle Cranial Fossa Originating in the Cavernous Sinus with Hyper-prolactinemia

I．はじめに

　中頭蓋窩の海綿状血管腫は，海綿静脈洞から発生するともいわれるが，今回著者らは，内外二葉の硬膜の間に存在し，海綿静脈洞内と強い癒着をもち，内分泌学的にhyperprolactinemiaを呈した海綿状血管腫の1症例を経験したので，文献的考察を加え報告する．

A 43-year-old female was admitted showing ab-normal feeling in the left eye region. Left facial hypesthesia and quadrantic hemianopsia of left eye were the detectable neurological findings. A plain skull x-ray film revealed a double floor and dilata-tion of the sella turcica. The tomogram of the sella turcica demonstrated a dilatation of superior orbital fissure. Caudocranial projection revealed a dilatation of foramen ovale. A computerized tomography scan revealed a slightly high density tumor which was enhanced slightly with a contrast medium in the para-sellar region and left middle fossa.
