Idiopathic Peripheral Pulmonary Artery Stenosis: An Unusual Cause of Ventilation-Perfusion Mismatch

Idiopathic peripheral pulmonary artery stenosis is a rare cause of ventilation-perfusion mismatch in adults. We report a 39-yr-old man with this entity. Pulmonary scintigraphy demonstrated findings indistinguishable from pulmonary embolism, and pulmonary angiography was necessary for accurate diagno...
