title: Pulmonary Artery Stenosis due to Lung Carcinoma: A Rare Cause of Dyspnea.
abstract: Acquired bilateral pulmonary artery stenosis in adults due to lung malignancy is infrequently reported. We describe an adult male who presented to us with chief complaints of dyspnea on exertion and one episode of hemoptysis. Two dimensional transthoracic echocardiography with color Doppler showed presence of an extra cardiac mass causing severe extrinsic compression of both the right and left pulmonary artery leading to high pressure severe tricuspid regurgitation and extension of the mass into the left atrium. Three dimensional transthoracic echocardiography clearly delineated the anatomy of the left atrial mass and its surrounding anatomical relationship. The diagnosis of non small cell lung carcinoma was confirmed by multidetector computed tomography (MDCT) and with MDCT guided biopsy with histopathology. Patient succumbed one month later due to an episode of massive hemoptysis.
