摘　　要：目的探讨回盲部结核CT增强扫描的影像特点。方法回顾性分析16例回盲部结核患者的CT及临床资料,均行CT平扫及增强扫描。结果14例肠壁不均匀增厚呈肿块样改变,管腔不同程度狭窄;2例表现肠壁广泛均匀增厚,肠腔无明显变窄。增强扫描13例为明显不均匀强化.2例为环状强化.1例为均匀强化。所有病例浆膜面均模糊.14例周围有渗出.腹膜受累12例。所有病例腹主动脉旁、肠系膜上均可见增大淋巴结.其中均匀强化10例.环状强化5例.1例合并钙化。结论回盲部结核主要表现为肠壁不均匀增厚,不均匀明显强化.肠腔狭窄,周围常有明显渗出.常合并增大淋巴结及肺内结核,CT增强扫描对回盲部结核的诊断有重要价值。Objective To explore the imaging characteristics of ileocecal tuberculosis by contrast-enhanced CT. Methods The ('T findings of 16 ileocecal tuberculosis patients were retrospectively analyzed. All cases underwent plain and enhanced CT scan.Results 14 cases showed inhomogeneous thickening of the intestinal wall and narrowing of the lumen, and 2 cases showed extensive and uniform thickening of the intestinal wall with no obvious narrowing of the lumen.The enhanced images showed that 13 cases were obviously heterogeneous enhancement,2 cases were ring-like enhancement,and 1 case was homogeneous enhancement.Blurred serosa surface was seen in all patients, with surrounding exudation in 14 cases and peritoneum involvement in 12 cases.In all cases, enlarged lymph nodes were found near the abdominal aorta and on mesentery, with homogeneous enhancement in 10 cases,annular enhancement in 5 cases and calcification in 1 casc.Conclusion Ileocecal tuberculosis is mainly characterized by inhomogeneous thickening and heterogeneous enhancement of the intestinal wall, as well as narrowing of the lumen.There is often obvious exudation around the intestines. Ileocecal tuberculosis often combines with enlarged lymph nodes and intrapulmonary tuberculosis.The enhanced CT scan is of great value for the evaluation of ileocecal tuberculosis.
