Expanding aneurysm of aberrant right subclavian artery. Case report and imaging evaluation.
We present a case illustrating the complementary role of CT and angiography in evaluation of a slowly expanding vascular thoracic mass representing aneurysmal enlargement in an aberrant right subclavian artery. Anatomy, embryology, incidence, and imaging of aberrant right subclavian artery, bicarotid trunk, and aneurysmal dilatation of the diverticulum of Kommerell are reviewed.
