Pineocytomaの1例

Pineocytoma: A case report

I．はじめに

　松果体部に発生する腫瘍のうち，松果体の固有実質より発生してくる成熟型の腫瘍であるpineocytcmaは極めて稀であり，報告も少なく，臨床像も明らかではない．われわれは興味ある経過を示したpineocytcmaの1例を経験したので，若干の文献的考察を加えて報告する．

A report on a rare case of pineocytoma is presented.

A 27-year-old woman visited our clinic because of a 3-month history of intermittent headaches and nausea. A CT scan revealed the presence of a marked obstructive hydrocephalus and mass without any con-trast enhancement in the pineal region. Immediately, V-P shunting was performed and resulted in relief of all symptoms. Ventriculography showed a complete occlusion at the aqueductus Sylvii and filling defect at the posterior part of the 3rd ventricle.
