目的探讨肺淋巴管平滑肌增生症腹部病变的CT表现。方法回顾性分析7例经病理证实的肺淋巴管平滑肌增生症,7例均作腹部CT扫描,对其腹部CT表现进行研究分析。结果7例患者中6例有腹部阳性表现:肾血管平滑肌脂肪瘤2例,其中1例合并胸导管增大、胸腔积液;腹膜后淋巴结肿大2例,合并腹水、胸腔积液1例;肝脏血管平滑肌脂肪瘤1例;腹膜后淋巴管肌瘤合并子宫肌瘤1例。结论肺淋巴管平滑肌增生症可并发腹部多脏器病变,CT扫描对发现和诊断其腹部病变具有重要意义。
Objective To investigate CT findings of abdominal lesions of pulmonary lymphatic smooth muscle hyperplasia. Methods Retrospective analysis of 7 cases of pathologically confirmed pulmonary lymphatic smooth muscle hyperplasia, 7 cases were made for abdominal CT scan, the abdominal CT findings were analyzed. Results Six of the seven patients had positive abdominal findings: 2 cases of renal angiomyolipoma, 1 case complicated thoracic duct enlargement and pleural effusion, 2 cases of retroperitoneal lymph node enlargement, 1 case of combined ascites and pleural effusion, 1 case of hepatic angiomyolipoma; 1 case of retroperitoneal lymphangioma with uterine fibroids. Conclusions Pulmonary lymphangitic smooth muscle hyperplasia may be associated with multiple organ diseases in the abdomen. CT scan is of great significance for the detection and diagnosis of abdominal lesions.
