Dear editor,rnPrimary pulmonary artery sarcoma (PPAS) is an uncommon neoplastic disease that can masquerade as pulmonary thromboembolism (PE). The nonspecific symptoms of this condition generally vary from mild dyspnea to severe respiratory distress and right heart failure. A male patient is discussed in this report who presented with fever, cough, and shortness of breath. An enhanced contrast computed tomography (EC-CT) scan revealed an intraluminal hypoattenuated area originating from the main pulmonary artery and extending further into the left pulmonary artery and the bilateral lobar pulmonary arteries, evidence for multiple lesions in both lungs. The spindle cell tumor, positive for smooth muscle actin, was pathologically diagnosed as PPAS using a needle biopsy of the lower lobe of the left lung.
