脳有鉤嚢虫症の1手術例

Cerebral Cysticercosis: Report of an operated case

I．はじめに

　有鉤嚢虫症は本邦では稀な疾患であるが^27），通常，脳および皮下，筋肉内に多発性に寄生することが多い^{10,17，18,28）}．今回われわれは，脳実質内の単発性の病巣がCTにより確認された脳有鉤嚢虫症の1症例を経験したので，若干の文献的考察を加えて報告する．

A rare case of cerebral cysticercosis is reported. The patient, a 49-year-old man, had been to Central America several times since 1963. He had an episode of seizure in March 1980 and again in August 1983, and was admitted to our hospital.

Skull X-ray, cerebral angiography, scintigraphy, EEG, CSF examination, Chest X-ray, blood and urine examinations were all normal. CT scan only revealed a small lesion in the left frontal lobe as a well cir-cumscribed round low density area with ring-like enhancement.

An operation was performed for a suspected brain tumor.
