目的 分析结核性腹膜炎(TBP) 的CT征象表现及诊断。方法 回顾性收集 2014年6月-2017年6月我院64例接受腹部 CT扫描检查的TBP确诊患者，分析其CT征 象表现，包括腹膜改变特征、腹腔积液 情况、腹腔淋巴结改变等。结果 TBP的 CT征象表现主要有：(1)壁腹膜增厚43例 (67.19%)，其中均匀增厚37例，不规则增 厚6例；(2)大网膜改变45例(70.31%)，表 现为大网膜增厚，以污迹样增厚(38例)最 为多见；(3)肠系膜改变48例(75.00%)， 表现为肠系膜软组织影，并可合并小结节 影及不同程度肠管扩张；(4)腹腔积液52 例(81.25%)，其中少量腹腔积液30例，中 量腹腔积液18例，大量腹腔积液4例；(5) 腹腔淋巴结改变13例(20.31%)，表现为增 大、增多，大小、数量不等。结论 TBP具 有壁腹膜增厚、大网膜增厚、肠系膜软组 织影、腹腔积液、腹腔淋巴结增大与增多 等CT征象表现，CT检查对其临床诊断有重 要价值。

Objective To analyze the CT findings and diagnosis of tuberculous peritonitis (TBP). Methods The clinical data of 64 patients with TBP who underwent abdominal CT scan in the hospital during the period from June 2014 to June 2017 were analyzed retrospectively. CT findings were analyzed, including peritoneal changes, ascites and abdominal lymph node. Results CT findings of patients with TBP mainly included (1) thickening of parietal peritoneum in 43 cases (67.19%) (uniform thickening in 37 cases, irregular thickening in 6 cases), (2) changes of omentum majus in 45 cases (70.31%), showing thickening of the omentum majus, stain - like thickening in 38 cases, (3) mesenteric changesin 48 cases (75.00%), showing mesenteric soft tissue shadow, with small nodule shadow and different degrees of dilated intestinal canal, (4) ascites in 52 cases(81.25%), little ascites in 30 cases, moderate ascites in 18 cases and large amount of ascites in 4 cases, (5)abdominal lymph node changes in 13 cases(20.31%), showing enlargement, increase, of different size and number. Conclusion CT findings of patients with TBP include thickening of parietal peritoneum, thickening of omentum majus, mesenteric soft tissue shadow, ascites and enlargement and increased of abdominal lymph nodes. CT is of great value in clinical diagnosis of the disease.
