綿片による異物肉芽腫の1例

A Case of Intracranial Foreign Body Granuloma Caused by Cotton Pledgets that Remained during Operation

I．はじめに

　脳外科の検査や手術の普及に伴い，頭蓋内への異物迷入残存による病変の報告が散見されるようになったが^1-4,7），今回われわれは，大脳鎌髄膜腫全摘出後約1年の経過で，痙攣の再発を起こしCTスキャンその他で髄膜腫再発と診断し再開頭を行ったところ，実は綿片による異物肉芽腫であった1例を経験したので，若干の考察を加え報告する．

A case of intracranial foreign body granuloma is reported which was caused by cotton pledgets after total removal of meningioma. A 46 year-old woman was admitted on July. 10, 1982, complaining of generalized convulsive seizures. CT and cerebralangiography revealed a left falx meingioma. The meingioma was totally removed under the left frontoparietal osteoplastic craniotomy. Microscopical findings were meningotheliomatous meningioma without malignancy. Despite the total removal, she developed two attacks of convulsion.
