Angiographic documentation of a persistent otic artery

Abstract

The persistent otic artery is a rare remnant of early fetal development that, to our knowledge, has been convincingly documented only once before with angiography. Other persistent vessels such as the trigeminal, hypoglossal, and proatlantal intersegmental arteries have been found to be associated with a variety of vascular anomalies. We believe we present the second case of a persistent otic artery documented by means of angiography and the first such case associated with multiple intracranial aneurysms.
