초록
Acquired bilateral pulmonary artery stenosis in adults due to lung malignancy is infrequently reported. We describe an adultmale who presented to us with chief complaints of dyspnea on exertion and one episode of hemoptysis. Two dimensionaltransthoracic echocardiography with color Doppler showed presence of an extra cardiac mass causing severe extrinsic compressionof both the right and left pulmonary artery leading to high pressure severe tricuspid regurgitation and extension of the mass intothe left atrium. Three dimensional transthoracic echocardiography clearly delineated the anatomy of the left atrial mass and itssurrounding anatomical relationship. The diagnosis of non small cell lung carcinoma was confirmed by multidetector computedtomography (MDCT) and with MDCT guided biopsy with histopathology. Patient succumbed one month later due to anepisode of massive hemoptysis.
