摘　　要：目的:探讨继发性肠系膜恶性病变的螺旋CT表现。方法:回顾性分析52例继发性肠系膜恶性病变患者的CT资料,腹腔内肿瘤和(或)癌性腹膜炎经病理证实或细胞学检查证实。着重观察肠系膜病变和原发肿瘤的CT表现特征。结果:肠系膜病变包括肿块影19.2%,系膜饼状改变3.8%,结节影53.8%,索条影67.3%,系膜密度增高71.2%,血管增粗伴或不伴有边缘模糊17.3%,系膜淋巴结增大42.3%。28例系膜结节中,均匀强化64.3%,环状强化14.3%,无强化21.4%。结论:螺旋CT可良好显示小肠系膜、横结肠系膜和乙状结肠系膜继发性恶性病变。Objective To investigate the CT features of secondary malignant tumors of the mesentery. Method Clinical information of fifty-two patients of secondary malignant tumors of the mesenteries was analyzed. Intra-abdominal tumors and/or cancerous peritonitis were identified by pathology and cytology assays. All of these patients received CT scaning. The present study focused on the secondary malignant peritonitis correlating to the involvement of subperitoneal space, peritoneal cavity and retroperitoneal space. Results The CT features of secondary malignant tumors of the mesenteries were shown as follows： mass sign, 19.2%; caked sign, 3.8%; nodular shadows, 53.8%; streaky appearances, 67.3%; increase in density of mesenteric fat, 71.2%; engorgement of the mesenteric vessels, 17.3%, enlargement of the mesenteric lymph nodes, 42.3%. Conclusions The spiral CT caning can efficiently demonstrate CT features of secondary malignant tumors of the mesentery.
