title: Unusual pulmonary lesion of vascular origin: a noninvasive diagnostic approach.
abstract: Despite the lack of pathologic confirmation, we believe that we are reporting an isolated pulmonary artery branch stenosis with poststenotic dilatation. The differential diagnosis of a solitary pulmonary lesion should include this unusual entity. Digital subtraction angiography offers a safe, minimally invasive way to confirm this anomaly.
