極めて稀な尿管原発転移性脳腫瘍の1剖検例

A Very Rare Autopsy Case of Metastatic Brain Tumor Originating from Ureteral Cancer

I．はじめに

　転移性脳腫瘍の原発巣として尿路系悪性腫瘍の頻度は4-5％といわれているが^8），尿管が原発巣となる例は非常に稀でありこれ迄報告をみない．今回，われわれは剖検により尿管原発の転移性脳腫瘍と判明した1症例を経験したので報告する．

We report here a very rare case of metastatic brain tumor originating from ureteral cancer which was veri-fied at autopsy.

An 88-year-old elderly woman was admitted to our department because of recurrent convulsions which started in March, 1987. Following this episode, right hemiparesis and speech disturbance appeared on June 6, 1987. Neurological examinations at admission on Au-gust 12, 1987 showed slightly disturbed consciousness, motor dominant aphasia, and dysphasia.

Enhanced CT scan demonstrated a large tumor in the left frontal lobe with perifocal edema, and a small mass in the right frontal lobe (Fig.1).
