Primary sarcoma of pulmonary artery is a rare tumor. A 46-year-old man was hospitalized because of dyspnea and hemoptysis. Pulmonary thromboembolism was suspected by chest X-ray, scintigraphy, and CT. But the mass had a to-and-fro movement above the pulmonary valve on pulmonary arterial cineangiography. We strongly suspected that it was primary neoplasm of pulmonary artery. The pulmonary artery was opened under cardiopulmonary bypass. The tumor arised pulmonary trunk and extended peripherally. The tumor was surgically removed as complete as possible, though a proxymal balloon embolectomy was unsuccessful. The histological finding was malignant fibrous histiocytoma of the pulmonary artery.
原发性肺动脉肉瘤是一种罕见的肿瘤。一名46岁男性因呼吸困难和咯血入院。胸部X线、闪烁扫描和CT检查怀疑为肺血栓栓塞。但在肺动脉血管造影中，肿块在肺动脉瓣上方有往返运动。我们强烈怀疑这是肺动脉原发性肿瘤。在体外循环下打开肺动脉。肿瘤起源于肺动脉干并向周围扩展。尽管近端球囊取栓术未成功，但肿瘤尽可能完整地被手术切除。组织学检查结果为肺动脉恶性纤维组织细胞瘤。
