title: [The malignant tumor of the pulmonary artery; report of a case].
abstract: Primary sarcoma of the pulmonary artery is rare. Diagnosis is difficult and often delayed; pulmonary embolism is part of the differential diagnosis. We treated a 46-year-old woman with progressive dyspnea. Computed tomography showed a lesion occupying the main pulmonary artery and peripheral branches on both sides. The pulmonary artery tumor, resected under cardiopulmonary bypass, was diagnosed pathologically as intimal sarcoma. Two weeks after the operation, the patient was feeling well and discharged from our hospital. Although the prognosis of pulmonary artery sarcoma is poor, early diagnosis and resection may prolong survival.
