Abstract

A 32 yr female was referred for surgery for Left atrial myxoma based on symptoms of dyspnea on exertion , palpitations and echocardiography revealing a left atrial mass , mostly likely a left atrial myxoma. On chest X ray , there was right lower lobe white out which instigated the need to perform a CT chest. On CT Chest a 10.9x14.2x13.6 cm (APxTRxCC) cm heterogenously hypodense mass was seen along the posterior and inferior aspect of right hemithorax. It showed multiple vascular channels within it and broad base towards posterior pleura. It had ill defined planes with left atrium and extension into the left atrium through right inferior pulmonary vein. It was causing compression of right descending pulmonary artery and right lower lobe bronchus with collapse of right lower lobe. Likey etiology was sarcomatous/malignant vascular mass. Patient was transferred to oncology department for further management
