High spatial resolution magnetic resonance imaging of cystic adventitial disease of the popliteal artery.

Abstract

High spatial resolution magnetic resonance imaging (MRI) of patients with cystic adventitial disease can demonstrate connections between cysts in the adventitia and the adjacent joint, which is important for successful treatment. The inability to identify these during surgery can lead to a recurrence; thus, high spatial resolution MRI has the potential to affect therapy. This article presents the high spatial resolution MRI findings of cystic adventitial disease in a series of three consecutive patients and discusses the relevance of these findings to the etiology and therapy.
