摘　　要：目的:探讨回盲部病变的CT表现特点及鉴别诊断,提高其诊断准确性。方法:回顾性分析40例临床拟诊为回盲部病变患者的临床和影像资料,结合病理结果探讨不同病变的CT表现特征。结果:40例中,26例恶性肿瘤(腺癌20例,间质瘤3例,淋巴瘤2例,神经内分泌癌1例),其中2例淋巴瘤合并肠套叠;14例炎症,一般感染性炎症8例(阑尾炎7例,急性重症胰腺炎并肠壁弥漫性增厚1例),肉芽肿性炎6例(包括肠结核2例,克罗恩病4例)。MSCT可显示回盲部病变的范围、肠壁增厚的方式、程度及强化特点,周围脂肪密度变化、淋巴结肿大及其他脏器转移。结论:回盲部不同病变的CT表现特点不同,有助于明确诊断。Objective：To investigate the CT features and differential diagnosis of ileocecal lesions,so as to improve the accuracy of diagnosis. Methods：40 cases of clinical diagnosis of ileocecal lesions underwent 64-slice spiral CT pre-contrast and enhanced scanning,the CT images were retrospectively analyzed, and combined with operation pathology results to analyze the CT features of different diseases. Results：40 cases of ileocecal lesions：26 cases with malignant tumors （20 adenocarcinoma, 2 lympho- ma, 3 stromal tumors, 1 neuroendocrine carcinoma） ; 14 cases with ir^flammatory diseases,8 infectious inflammation （including 7 appendicitis, 1 acute severe pancreatitis caused the intestinal wall diffuse thickening） ;6 cases granulomatous inflammation （2 tuberculosis, 4 Crohn＇s diseases）, also 2 cases of lymphoma with intussusception. The 64-slice spiral CT clearly displayed the ileocecal lesions characteristics involving the range and the degree of intestinal wall thickening, the enhanced features, the surrounding fat clearance density, the lymph node enlargement, and the metastasis of other organs. Conclusion：The CT features of different ileocecal lesions are different,which is helpful to make a definitive diagnosis.
