외상성 후이개동맥-내경정맥루로 인하여 발생한 이명

초록

A patient suffering from arteriovenous fistula which developed after a traffic accident was recently treated. The patient noticed pulsatile tinnitus in the right orbital region two months after the accident. On the first visit, clinical impression of this case was diagnosed as a carotid-cavernous fistula. But the angiography documented a fistula between the posterior auricular artery and internal jugular vein. Although rare, this arteriovenous fistula should have been included in the differential diagnosis of pusatile tinnitus in the orbital region. An arteriovenous fistula between the posterior auricular artery and internal jugular vein has not previously been reported.
