BACKGROUND Isolated pulmonary artery vasculitis is an uncommon cause of pulmonary artery aneurysm with very few reported cases in the literature. PATIENTS AND METHODS We hereby present the case of a 70-year-old man with occasional episodes of exertional chest discomfort. Our investigations revealed an expanding aneurysm of the main pulmonary artery extending to the proximal portion of the right branch. The patient successfully underwent replacement of the main pulmonary artery with a homograft. RESULTS Histopathological examination revealed images of vasculitis with numerous multinucleated giant cells. The patient postoperative course was uneventful. CONCLUSION Management of pulmonary artery aneurysm secondary to isolated pulmonary artery vasculitis is not well studied, and no clear guidelines currently exist in the literature.
