“…In addition, the differential diagnosis between thromboembolism and sarcoma is difficult, as in most cases the diagnosis is determined by examining resected or autopsy specimens (6). Nevertheless, a reliable diagnosis of pulmonary artery sarcoma has been reported using enhanced CT or transesophageal echocardiography (8,9). PET is also useful for differentiating the tumor from a thromboembolism (10), which shows increased uptake in the area of the tumor, especially in patients without extramural invasion such as the present case.…”

Primary Leiomyosarcoma of the Pulmonary Artery: A Case of a 20-Month Survivor after Incomplete Surgical Resection

et al. 2012

We report a 53-year-old man who presented with dyspnea and low-grade fever. Cardiac ultrasound showed pulmonary hypertension and an ill-defined echogenic mass within the pulmonary trunk. Computed tomography scan revealed an inhomogeneous mass which filled the main pulmonary trunk with near-total occlusion, and extended into both pulmonary arteries. Anticoagulant therapy was administered based on a presumptive diagnosis of pulmonary thromboembolism. Positron-emission tomography scan was useful for differentiating the mass, which was determined as a pulmonary artery sarcoma by surgical resection. Although complete resection was impossible, the patient survived for 20 months with adjuvant chemotherapy and medical treatment.
