【摘要】 目的 探讨结核性腹膜炎的CT诊断价值。 方法 回顾性分析2009年10月-2010年7月22例经手术、病理或抗结核治疗确诊的结核性腹膜炎CT完整资料。主要观察:淋巴结、腹水、腹膜、系膜、网膜改变。 结果 淋巴结肿大12例，增强后呈“环状”强化改变。腹腔积液15例，少～中量12例，聚集在肠系膜根部、结肠旁沟及盆腔较多，CT值20～28HU。腹膜增厚16例，其中14例均匀光滑增厚，10例明显强化；大网膜增厚15例，其中饼状增厚2例、污垢样增厚9例、结节样4例。肠系膜增厚18例，3例肠袢聚集、粘连。伴有其他脏器结核13例。 结论 CT对诊断和鉴别诊断结核性腹膜炎具有较大的临床价值，结合临床多数结核性腹膜炎可作出正确诊断。【Abstract】 Objective To evaluate the diagnostic value of CT scan for tuberculotic peritonitis. Methods The complete CT image data of 22 patients with tuberculotic peritonitis confirmed by surgical, pathologically, or therapeutic procedures from October 2009 to July 2010 were retrospectively analyzed. The changes of lymph nodes, ascites, thickened peritoneum, mesentery and greater omentum were observed. Results In 22 patients, enlargement and rim enhancement of lymph nodes were found in 12; ascites with CT value of 20-28 HU was in 15, of whom 12 had small or middle amount of effusion which located in mesentery or abdominal cavity; thickened parietal peritoneum was in 16, including smooth peritoneum in 14 and evident enhancement in 10; thickened greater omeutum was in 15, including cake-like thickening in 2, filth-like thickening in 9 and tuber-like thickening in 4; thickened mesentery was in 18, including intestinal loop adhesion in 3.A total of 13 patients were combined with other tuberculosis. Conclusion CT scan is very important in diagnosing and differentially diagnosing tuberculous perinitis.
