目的：明确腹腔、腹膜后间隙结核的ＣＴ表现与病理基础的相关性。材料和方法：对１３例淋巴结结核、２例结核性腹膜炎以及２例淋巴结结核合并结核性腹膜炎采用ＣＴ增强扫描，观察其病变的形态、密度及解剖分布。结果：淋巴结结核表现为淋巴结增大，增强扫描呈环状强化，可融合成多房样肿块，主要分布于系膜、网膜及Ｌ２平面以上的腹膜后间隙；而结核性腹膜炎ＣＴ表现为腹水密度较高，网膜、系膜上斑片和结节影，网膜增厚，卷缩成不规则肿块，受累的系膜、网膜与肠曲粘连、固定。结论：淋巴结结核病理改变决定其ＣＴ增强扫描特征以及优势解剖分布；ＣＴ扫描可揭示结核性腹膜炎解剖病理特点。
Objective: To clarify the relationship between CT findings and pathological basis of abdominal and retroperitoneal space tuberculosis. MATERIALS AND METHODS: Thirteen cases of tuberculous peritonitis, two cases of tuberculous peritonitis and two cases of tuberculous peritonitis with tuberculous peritonitis were examined by CT scanning to observe the morphology, density and anatomy of the lesions. Results: Lymph node tuberculosis showed lymph node enlargement, enhanced scan ring enhancement, can be integrated into multi-room mass, mainly in mesangial, omentum and L2 plane above the retroperitoneal space; and tuberculous peritonitis CT showed ascites High density, omentum, mesangial patches and nodules, retinal thickening, curled into irregular lumps, involvement of mesangial, omentum and intestinal song adhesion, fixed. Conclusion: The pathological changes of lymph node tuberculosis determine the features of CT enhanced scanning and the superior anatomic distribution. The CT scanning can reveal the anatomical and pathological features of tuberculous peritonitis.
