Pulmonary artery sarcoma: a rare cause of lung masses and tumor emboli

Abstract

We reported here a case of pulmonary artery sarcoma. The patient presented with progressive dyspnea on exertion for 2 months. Chest radiography showed a large lobulated mass in the right lower lung field. Chest CT scan showed 2 pulmonary masses in the rightmiddle lobe and the right-lower lobe, with extensive filling defects in the right and left pulmonary arteries. A core needle biopsy of the larger mass showed an undetermined type of sarcoma. Pulmonary arteries were considered the primary origin of the sarcoma. Pulmonary endarterectomy with tumor debulking was performed to relieve the patient’s symptoms in a combination with adjuvant chemotherapy.
