目的探讨腹内淋巴结结核的影像学诊断价值。方法对经临床病理证实的腹内淋巴结结核２７例进行分析，所有病例均经多种影像学检查。结果典型的ＣＴ表现是环形强化的肿大淋巴结，淋巴结内钙化少见但有重要诊断价值。Ｂ超显示大于２．０ｃｍ的肿大淋巴结肉呈不均回声，部分伴有无回声；小于 ２．０ ｃｍ者内部回声均匀。胃肠钡餐造影意义在于检出淋巴结结核合并胃肠道结核或直接侵犯小肠。腹部Ｘ线平片可发现淋巴结钙化和肠梗阻。结论各种影像学检查对腹内淋巴结结核均有一定诊断价值，以ＣＴ诊断价值最高，Ｂ超更适合于复查病例。
Objective To investigate the imaging diagnosis of intra-abdominal lymph node tuberculosis. Methods Twenty-seven cases of intra-abdominal lymph node tuberculosis confirmed by clinical pathology were analyzed. All the cases were examined by multiple imaging. Results The typical CT findings were ring-shaped enlarged lymph nodes, which were rare in the lymph nodes but had important diagnostic value. B-ultrasound showed greater than 2.0cm swollen lymph nodes were uneven echo, with some no echo; less than 2.0 cm internal echo uniform. The significance of gastrointestinal barium meal imaging is the detection of lymph node tuberculosis with gastrointestinal tuberculosis or direct violations of the small intestine. Abdominal X-ray can be found in lymph node calcification and intestinal obstruction. Conclusion Various imaging studies have certain diagnostic value for intra-abdominal lymph node tuberculosis, with the highest diagnostic value of CT, B-ultrasound is more suitable for review cases.
