An incidental vascular abnormality was identified in a female patient in her 70s with a history of malignant lymphoma. Contrast-enhanced computed tomography (CT) scans revealed a pulmonary artery aneurysm (PAA) originating at the A10 branch of the right pulmonary artery (10 × 9 × 9 mm in size), which involved three distal branches at the aneurysmal sac. Retrospectively, this PAA was identified on CT images two years prior, and has been growing since. Endovascular embolization was performed with microcoils that were placed in the aneurysmal sac and the distal and proximal sites of the parent artery, achieving complete resolution of the PAA without complications. Coil embolization can be one of the treatment options in management of the unruptured PAA, although further investigations are necessary.
