title: Dyspnea lusoria: compression of the pulmonary artery by a Kommerell's diverticulum.
abstract: We report a rare case of Kommerell's diverticulum presenting as dyspnea on exertion. After careful physical examination, selective imaging tests demonstrated a significant flow abnormality in the left pulmonary artery caused by an aneurysm of the descending aorta in the area of the ligamentum arteriosum.
