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。 Objective To explore the imaging features of gastrointestinal tuberculosis. Methods Nineteen cases diagnosed as gastrointestinal tuberculosis were retrospectively analyzed, and the imaging changes of lesion, shape, margins and surrounding tissues were analyzed. Results Among the 19 patients, 1 had gastric antrum, 1 had jejunal tuberculosis, 15 had terminal ileum, 15 had ileocecal tuberculosis, 1 had ileocecal and ascending colon, and 1 had transverse tuberculosis. The diagnosis of this group of patients, in addition to gastric cancer, ileocecal tuberculosis in 1 case of misdiagnosis, the rest are consistent with the pathological diagnosis, the misdiagnosis rate was 10.5%, the accuracy rate of 89.5%. Conclusion Gastrointestinal tuberculosis has some characteristic features of imaging, but must be combined with clinical history, pathology, bacteriological examination can make a clear diagnosis.
