摘　　要：目的:研究腹部淋巴结结核的CT表现,提高该疾病的诊断及鉴别诊断水平。方法:搜集14例经病理证实的腹部淋巴结结核,观察受累淋巴结的解剖分布、形态及强化方式特征。结果:肠系膜淋巴结受累8例,胰周小网膜10例,脾门1例,腰3平面以上腹膜后间隙6例,脾肿大10例。多房环形强化10例,均匀强化3例,环形强化1例。结论:腹部淋巴结结核CT表现具有一定的特征性,有助于该疾病的诊断及鉴别诊断。Objective：To study the CT findings of tuberculosis of abdominal lymph nodes so as to improve its diagnosis and differential diagnosis. Methods： CT images of tuberculosis of abdominal lymph nodes proved histologically in 14 patients were retrospectively analyzed,including anatomical distribution, morphologic features and mode of contrast enhancement. Results： Mesenteric lymph nodes were involved in 8 of 14 patients,the peripancreatic lesser omentum nodes in 10 cases,the nodes in hilum of spleen in one case,the nodes in retroperitoneal space above third lumbar vertebra in 6 cases. Ten cases showed enlarged spleen. Multi-locular and circular enhancement was shown in 10 cases （71.4%）, homogeneous enhancement in 3 cases （21.4% ）, and singular circular enhancement in 1 case （7. 1% ）, respectively. Conclusions： CT appearance of tuberculosis of abdominal lymph nodes is characteristic and has great use for diagnosis and differential diagnosis.
