Fibromuscular dysplasia of the posterior auricular artery: an unusual aneurysmal lesion.
A 67-year-old patient was admitted to hospital with a pulsatile mass behind his left ear. The clinical diagnosis was a posterior auricular artery aneurysm, and this was confirmed on Digital Subtraction Angiography. The aneurysm was excised and sent for pathology. The findings were felt to be consistent with fibromuscular dysplasia. This appears to be only the second reported case in the literature of a posterior auricular artery aneurysm.
