MR Imaging of Aneurysm of an Aberrant Right Subclavian Artery

Abstract

Magnetic resonance (MR) imaging was performed for evaluation of a right paramediastinal mass in an asymptomatic 84-year-old woman. An aneurysm of an aberrant right subclavian artery was diagnosed. This rare complication of a common congenital anomaly and the use of MR in evaluation is discussed.
