Primary pulmonary artery sarcoma: difficult differential diagnosis from chronic pulmonary thromboembolism.
Pulmonary artery sarcoma is a rare malignant tumor. The disease is frequently misdiagnosed as chronic pulmonary thromboembolism because of the similar clinical and radiologic findings. We present a case of primary pulmonary artery sarcoma that was misdiagnosed as chronic pulmonary thromboembolism, and discuss the clinical presentation, diagnosis, and outcome.
