【摘要】 目的:探讨肠系膜孤立性肿块的CT表现及其诊断和鉴别诊断价值。材料和方法:回顾性分析经手术病理证实的12例肠系膜孤立性肿块的CT表现。结果:间质瘤1例、恶性间质瘤1例、畸胎瘤1例、恶性淋巴瘤2例、脂肪肉瘤1例、恶性神经鞘瘤2例、恶性腹膜间皮瘤1例、平滑肌肉瘤1例和Castleman病1例、肠系膜上动脉瘤1例。术前准确定位11例(11/12),正确判断良、恶性10例(10/12),正确判断病理组织类型6例(6/12)。结论:CT是诊断肠系膜孤立性肿块的重要影像学手段,能明确肿瘤范围以及肿瘤与周围组织的关系,部分典型病例可明确诊断。更多还原

【Abstract】 Purpose:To evaluate CT signs of the solitary mesenteric mass.Materials and Methods:The CT findings of 12 cases with a solitary mesenteric mass proved by surgery and pathology,were analyzed retrospecticvely.Results:There were benign gastrointestinal stromal tumor(n=1),malignant gastrointestinal stromal tumor(n=1),teratoma(n=1),lymphoma(n=2),Lipo sarcoma(n=1),malignant schwannoma(n=2),malignant peritoneal mesothelioma(n=1),leiomyosarcoma(n=1),Castleman diseases(n=1),superior mesenteric artery aneurysm(n=1).Of 12 cases on CT scans,the accurate preoperative localization was in 11 cases,accurate prediction of benignancy or malignance in 10 cases,and accurate prediction of pathology in 6 cases.Conclusion:CT plays an important role in the diagnosis of the solitary mesenteric mass,and is very helpful in clarifying the nature and the extent of the tumors,partial cases may determine its histological origin with some characteristics on CT scans.更多还原
