天幕内硬膜動静脈奇形—1治験例と文献的考察

Tentorial Dural Arteriovenous Malformation:a Case Report

Ⅰ．はじめに

　特発性硬膜動静脈奇形はNewton（1968）^23）の報告したごとく，後頭蓋窩に生じることが多く，症状，治療，病理所見とも脳実質内動静脈奇形とは明らかに区別すべき疾患である．

　最近本邦においても注目され，後頭蓋窩に限定すると22例を数えるに至った^{11，12，15，16，25，26，30，36，38-41，43，44，47）}．我々も最近本例を経験したので，これまで報告のあった外国例90例^{1-10，13，14，17-24，27-29，31-35，37，42，44-46）}と本症例^15）を含め合計112例の検討結果を併せ報告する．

A ease of tentorial dural AVM was reported.

A 52 years old man came to the Jichi Medical School hospital on July 29, 1971, with the chief complaints of intermittent left exophthalmos, diplopia and left blepharoptosis, which had been noted since March of 1974. He had episodes of severe headache attack since 3 years prior to the hospital visit.

Angiography done at the out-patient department demonstrated the dural AVM with the nidus in the left tentorium.
