脳マンソン孤虫症

Sparganosis Mansoni of the Brain:A case report

I．はじめに

　マンソン裂頭条虫の幼虫であるマンソン孤虫の人体寄生部位は，通常，四肢体幹の皮下組織，筋肉内であり，脳寄生の報告はこれまで2例の剖検例^3,7）がみられるのみである．われわれは今回，けいれんで発症した脳マンソン孤虫症を経験した．これは頭蓋内から生きたマンソン孤虫の摘出例としては，文献上初めての報告と思われる．

A patient with Sparganum mansoni in the brain was reported. To date this tapeworm has been reported to be found in only two autopsied human brains in the literature. This is, to our knowledge, the first report in the world in which a live intracranial Sparganum mansoni was successfully removed. This 33-year-old Korean woman had complained of generalized tonic-clonic convulsion during the past five years.

Right frontotemporal craniotomy was performed and a live Sparganum mansoni was removed from the subdural space.
