结核性腹膜炎的CT表现

目的 分析结核性腹膜炎的CT表现特点，以提高其诊断水平。方法 回顾性分析26例经临床病理证实结核性腹膜炎的CT表现．结果 （1）腹水21例，其中17例表现为高密度腹水（CT值〉20HU），4例表现为低密度腹水，少量11例，中量7例，大量3例；（2）壁腹膜光滑增厚15例，3例轻微不规则增厚，增强扫描有强化：（3）肠系膜改变26例，表现为系膜增厚成团，呈结节状．片状或“污点”状改变；（4）大网膜改变19例，表现为饼状增厚、结节状或“污点”状改变；（5）伴腹腔淋巴结肿大8例，5例环形强化，3例无明显强化。结论 污迹腹膜增厚及少，中量高密度腹水，为结核性腹膜炎常见CT表现：鉴别诊断主要与癌性腹膜炎鉴别。

CT findings of Tuberculous Peritonitis

Objective To discuss the CT findings of tuberculous peritonitis（TBP） to improve the diagnostic level. Methods CT findings of 26 cases with tuberculous peritonitis（TBP） proved pathologically and clinically, were retrospectively analyzed. Results The CT findings：（1）Ascites （n=21）, hyperdense peritoneal effusion （n=17 CT value 〉 20HU ）; （2） Thickened parietal peritoneum, smoothly （n=15）, and irregularly （n=3）. parietal peritoneum enhencement after contrast injection; （3） Thickened mesentery with nodular or smudged shadows （n=26）; （4） Thickened greater omental （n=19）; （5） Lymph nodes enlargement of peritoneal cavity （n=8）, no obvious chang（n=3）. Conclusion Thickened parietal peritoneum with smudged shadows and hyperdense peritoneal effusion are commonly seen on CT finding of the tuberculous peritonitis. Metastatic tumor of peritoneum is the main disease needed to be differentiated with.
