【摘要】 目的探讨结核性腹膜炎的CT平扫表现特征。方法回顾性分析46例有CT扫描资料的结核性腹膜炎患者,其中经手术病理证实6例,腹腔穿刺证实2例,腹腔镜检证实4例,试验性治疗诊断34例。观察内容包括结核性腹膜炎累及壁腹膜、大网膜、肠系膜及腹膜后间隙的CT表现特征。结果 (1)壁腹膜增厚33例,其中均匀、光滑增厚27例,局部不规则增厚6例;(2)腹腔积液31例,其中20例为少量积液;(3)大网膜增厚26例,表现为污迹样增厚22例,饼状增厚2例;(4)肠系膜受累32例,其中9例合并小结节影:(5)淋巴结增大16例;(6)肠壁增厚1例,肠间距增宽2例。结论结核性腹膜炎CT平扫的主要表现有少量腹腔积液、均匀性腹膜增厚、大网膜污迹样增厚,以及肠系膜、肠管受累与腹腔淋巴结增大,CT平扫能为结核性腹膜炎的诊断提供重要信息。更多还原

【Abstract】 Objective To explore features of the plain CT scan in patients with tuberculous peritonitis.Methods Forty-six tuberculous peritonitis patients with data of abdominal plain CT scan were retrospectively reviewed,including 6 cases proven by postoperation pathology,2 cases diagnosed by abdominal puncture,4 cases confirmed by laparoscopy,and 34 cases identified by experimental treatment.The CT features of tuberculous peritonitis involved in parietal peritoneun,peritonealcavity,greater omentum,mesentery,and retroperitoneal space were observed.Results The main features in the plain abdominal CT scan of tuberculous peritonitis appeared as follows:①Thickened parietal peritoneum in 33 cases(71.7%),including smooth in 27 and irregular in 6;②Ascites in 31 cases(67.4%),of which 20 cases revealed a small amount of effusion;③Thickened greater omentum in 26 cases(47.8%),including smear like shape in 22 and caked sign in 2;④Mesenteric thickening in 32 cases(69.6%)with concurrent small nodular shadows in 9 cases;⑤Enlarged lymph nodes in 16 cases(34.8%).⑥Bowel wall thickening in 1 case.Conclusion The main plain CT scan features of tuberculous peritonitis may appear as a small quantity ascites,smooth thickening and enhanced parietal peritoneum,thickened greater omentum with smear shadows,involvement of mesentery and enlargement of lymph nodes.The plain CT scan can provide important information for the diagnosis of tuberculous peritonitis.更多还原
