Pulmonary artery sarcoma(PAS) is a rare and lethal neoplasm that is usually diagnosed during surgery or autopsy. Early diagnosis and radical surgical resection offer the only chance for survival. However, making a preoperative histopathological diagnosis is quite difficult. We encountered a 57-year-old woman presenting a PAS that mimicked a pulmonary thromboembolism.After confirming a definitive diagnosis using a catheter suction biopsy, we successfully performed a right pneumonectomy via a median sternotomy without cardiopulmonary bypass. Eighteen months after surgery, no recurrence was observed.
