Pulmonary Artery Aneurysm: A Rare Case Report

Pulmonary artery aneurysm is a rare entity involving aneurysmal dilatation of the main pulmonary artery. It is associated with structural cardiac anomalies, structural vascular abnormalities, pulmonary artery hypertension, vasculitis and infection. In some cases, it can also be idiopathic. Clinical presentation may vary in different patients and are nonspecific. Treatment is usually surgical intervention once diagnosed. We have presented one such case of a patient whose Computed Tomography (CT) scan showed a large aneurysm of descending branch of pulmonary artery.
