興味ある経過を示したcavernous sinusitisの1症例

Interesting Radkdiological and Pathological Fimdings of the Internal Carotid Artcry observed in a Case of Cavernous Sinusitis

Ⅰ．はじめに

　海綿静脈洞部の炎症により海綿静脈洞症候群（cavcrn-ous sinus syndrome）を示した症例の報告は少なく，またそのほとんどが剖検所見の記載に止まっている．

　我々は左側の非拍動性眼球突出にて発症し，経過中両側のcavernous sinus syndromeを示した1症例において，数回にわたり頸動脈撮影を行い，一側内頸動脈の完全閉塞のほかに，他側においては，内頸動脈の海綿静脈洞部（cavernous portion）に裏状動脈瘤様のopacificationが認められた．X線所見と剖検所見を主に報告し，あわせて考察を加える．

A 47-year-old man was admitted to the neurosurgical department of Nagasaki University Hospital with complaints of high fever, deteriorated conciousness and nonpulsating exophthalmus on the left side. The first carotid angiography which had been done 2 days prior to admission, showed only an irregular narrowing in the cavernous portion of the left carotid artery. The right carotid angiogram did not show any recognizable abnormality. The second angiography which was performed 4 days after the admission, revealed an cylindrical aneurysmal opacification about 0.8cm in diameter in the left intracavernous portion.
