摘　　要：目的探讨多排螺旋CT（MDCT）在原发性肺动脉肉瘤（PPAS）诊断中的临床价值，以提高对原发性肺动脉肉瘤的认识。方法本文收集17例肺动脉肉瘤患者CT及临床资料并详细分析此类疾病的I临床症状、MDCT特征。结果MDCT所见17例确诊PPAS患者中肿瘤位于主肺动脉同时向左、右肺动脉干延伸者共12例。其中同时累及右室流出道及肺动脉瓣者2例。左肺门结构不清者2例；肿瘤位于右肺动脉干并同时累及右上肺动脉者2例；位于主肺动脉并同时累及左肺动脉干者l例；肿瘤位于双侧肺动脉起始部者1例；肿瘤位于主肺动脉同时累及肺动脉瓣者1例；10例纵隔淋巴结增大，2例侧支血管形成。受累肺动脉不同程度扩张及动脉内持续性软组织充盈、肺动脉边界不清。结论MDCT具有优良的时间、空间和密度分辨率，对诊断肺动脉肉瘤有显著优势，不仅可清晰显示病变的范围、程度及流出道的受累情况，而且可同时检测肺、支气管及纵隔情况。Objective To investigate the application value of multi-detector spiral computed tomography （MD（＇T） in the diagnosis of primary pulmonary artery sarcoma（PPAS）. Methods According to the clinical data of 17 PPASpatients, their clinical features, MDCT findings and pathology were carefully analyzed. Results In 17 patients, the tumors were located in the main pulmonary artery and extended to the left and right pulmonary artery in 12 cases. Among them, 2 cases involved the pulmonary valve and the right ventricular outflow tract, the structure of the hilum ofleft lung were unclear in 2 cases. The tumor in the right pulmonary artery and involved the upper right pulmonary artery in 2 cases, tumor located in the main pulmonary artery and involved the left pulmonary artery in 1 ease,the beginning part of the tumor located in a double pulmonary in 1 case,the tumor located in the main pulmonary artery and involved the pulmonary valve simultaneously in 1 case. 10 cases with mediastinal lymph node enlargement and 2 cases with collateral vessels. The invoved main pulmonary artery showed expansion in various degrees, soft tissue filling defects and ill-defined margins. Conclusion MDCT can display the charectristics of PPAS clearly, and it plays an important role in the diagnosis of PPAS.
