Sarcoma of the pulmonary artery is a rare tumor. The histopathologic features of these tumors differ widely, with leiomyosarcomas representing less than 20% of all pulmonary sarcomas. Diagnosis is very difficult because most of the cases have no specific clinical signs: the major differential diagnosis is that of pulmonary thromboembolism. We report the case of a 45-year-old woman, who was first treated for pulmonary thromboembolism until the diagnosis of an intravascular growing tumor was made by means of computed tomography, pulmonary angiography and nuclear magnetic resonance tomography. The patient underwent right pneumonectomy and microscopically a leiomyosarcoma of the right pulmonary artery was found.
肺动脉肉瘤是一种罕见的肿瘤。这些肿瘤的组织病理学特征差异很大，其中平滑肌肉瘤占所有肺肉瘤的比例不到20%。由于大多数病例没有特异性临床症状，诊断非常困难：主要的鉴别诊断是肺血栓栓塞症。我们报告一例45岁女性病例，该患者最初因肺血栓栓塞症接受治疗，后来通过计算机断层扫描、肺血管造影和核磁共振断层扫描确诊为血管内生长肿瘤。患者接受了右肺切除术，显微镜检查发现为右肺动脉平滑肌肉瘤。
