Percutaneous Management of Segmental Pulmonary Artery Aneurysm in a Patient Without Pulmonary Artery Hypertension

Purpose: The aim of this article is to report the percutaneous management of a case of idiopathic segmental pulmonary artery aneurysm (SPAA) in a patient without pulmonary arterial hypertension. Materials and Methods: A 69-year-old female was referred for the evaluation of an incidental finding of a solitary right pulmonary nodule on chest radiograph (CR). Chest computed tomography and pulmonary arteriogram findings were consistent with a solitary SPAA. Successful percutaneous endovascular coil occlusion of the SPAA was performed. Discussion: Segmental pulmonary artery aneurysm considered on CR should be confirmed on initial contrast chest computed tomography. Conclusions: Endovascular coil occlusion is a minimally invasive therapeutic option for idiopathic SPAA.
