目的 探讨系统性红斑狼疮心血 管及淋巴结HRCT表现特点。方法 回顾性 分析359例经临床证实系统性红斑狼疮累 及心血管及淋巴结的CT表现。结果 男性 30例，女性329例。胸主动脉或冠状动脉 钙化阳性例数为79人，有71例患者发现心 包积液，22例患者心影增大，主动脉扩张 7例，肺动脉扩张16例。主动脉瓣及二尖 瓣发现钙化分别为12例和8例。淋巴结病 变中，有197例患者腋窝淋巴结有异常， 88例患者纵隔淋巴结有异常。结论 CT是 评估SLE心血管及淋巴病变的有效工具， 主动脉及冠脉钙化、心包积液、纵隔及腋 窝淋巴结增多增大等是SLE累及心血管淋 巴的常见表现。

Objective To investigate HRCT of systemic lupus erythematosus associated with cardiovascular and lymph nodes diseases. Methods The CT characteristics of 359 cases with systemic lupus erythematosus clinically proven involving the cardiovascular system and lymph nodes were analyzed retrospectively. Results There are 30 men and 329 women. The positive number of patients with thoracic aorta or coronary artery calcification was 79, 71 patients found pericardial effusion, 22 patients with increased heart shadow, 7 cases wtih aortic dilatation, pulmonary artery dilatation in 16 cases. There were 12 and 8 cases with aortic valve and mitral valve calcification, respectively. For lymph node lesions, there were 197 cases wtih abnormal axillary lymph nodes and 88 patients with abnormal mediastinal lymph nodes. Conclusion CT is an effective tool to assess SLE cardiovascular and lymphatic disease. Aorta and coronary calcification, pericardial effusion, increasing or swelling lymph nodes in mediastinal and axillary are the common manifestations of SLE involving cardiovascular and lymphatic system.
