内頸動脈瘤と癒着したHGH産生下垂体腫瘍の1例

A Rare Case of HGH Producing Pituitary Adenoma in Direct Contact with an IC Medial Type Aneurysm.

I．はじめに

　下垂体腫瘍と脳動脈瘤の合併例は過去に種々報告されている．しかし，下垂体腫瘍に脳動脈瘤が直接接している症例の外科的治療の報告はいまだなされていない．われわれは，下症体腫瘍と脳動脈瘤が直接接している症例を経験した．下垂体腫瘍に直接接した脳動脈瘤の外科的治療例としては，文献上，本症例が初めての報告と思われる．

A rare case of HCH producing pituitary adenomawhich was in direct contact with right IC medial typeaneurysm was reported. A 60-year-old woman was ad-mitted to our clinic in February, 1981, for the acromegalicfeatures, who was treated by 5 mg/day of CB-154 since1976 under the diagnosis of HGH secreting adenoma.The diagnosis of bitemporal hemianopsia was made in1977, but it was disappeared at the time of admission toour clinic.
