Abstract
UNLABELLED: Primary pulmonary artery sarcoma (PAS) is a rare and highly lethal tumor. Here, we report a case of a 53-year-old female with PAS who was initially diagnosed with chronic pulmonary thromboembolism (PTE) based on the results of a transthoracic Doppler echocardiogram, a contrast-enhanced computed tomography angiography, and a ventilation/perfusion lung scan. CONCLUSION: We emphasize the difficulties in diagnosing PAS, the need to investigate this neoplasm in the differential diagnosis of PTE, the diagnostic value of different imaging techniques in the identification of the the tumor, and the efficacy of adjuvant chemotherapy in prolonging survival.
