19例胃肠结核的影像学分析

目的 探索胃肠结核的影像学特点。方法回顾分析经确诊为胃肠结核19例病例，从病灶部位、形态、边缘、周围组织的影像改变进行分析。结果19例患者中，胃窦部结核1例，空肠结核1例，末端回肠、回盲部结核15例，回盲部及升结肠同时受累1例，横结肠结核1例。本组病例影像诊断，除胃结核、回盲部结核各1例误诊外，其余均与病理诊断相符合，误诊率为10.5%，准确率89.5%。结论胃肠结核的影像表现有一定的特征性，但必须结合临床病史，进行病理、细菌学检查才可做出明确的诊断。

The imaging analysis of gastrointestinal tuberculosis in 19 cases

Objective To analyze the imaging features of gastrointestinal tuberculosis. Methods 19 patients with gastrointestinal tuberculosis were analyzed retrospectively. The imaging changing in shape, location, edge and surrounding tissue of lesion were involved. Results We found one stomach tuberculosis,one jejunum tuberculosis, 15 terminal ileum or ileocecal junction tuberculosis, one terminal ileum and ascending colon tuberculosis, one transverse colon tuberculosis in 19 patients. Except for misdiagnosis in one ileocecal junction tuberculosis and one stomach tuberculosis, the other patients got a correct diagnosis in according with pathological diagnosis. The rate of misdiagnosis was 10.5% and the rate of accuracy was 89.5%. Conclusion Gastrointestinal tuberculosis have some imaging features, but diagnosis should be identified according to clinical history, pathology and bacteriology detection.
