腹茧症的影像诊断

Radiological diagnosis of abdominal cocoon

目的探讨腹茧症的影像特点,提高术前诊断水平。方法回顾性分析经手术病理证实的腹茧症6例,术前均进行立位腹部 X 线平片和腹部 CT 检查,4例同时行胃肠道钡剂造影,复习其影像表现。结果 6例立位腹部 X 线平片中3例诊断为肠梗阻。4例胃肠道钡剂造影,均可见小肠交错盘绕成团,呈"菜花"状或"手风琴"状表现。6例 CT 检查,均可见小肠聚集成团,其周围可见膜样的囊状物将其包裹。结论对患者进行胃肠道造影时观察到"菜花"状征象,或 CT 检查时观察到小肠聚集成团被一层膜样物包裹,应考虑到腹茧症的可能。

Objective To investigate the imaging characters of abdominal cocoon. Methods Six cases of abdominal cocoon proved by surgery and pathologic findings were retrospectively analyzed. Abdominal plain X-ray and CT were performed in 6 cases. The gastrointestinal barium meal series were undergone in 4 cases. The imaging findings were analyzed. Results Abdominal plain X-ray suggested intestinal obstruction in 3 of 6 cases. The gastrointestinal barium meal showed ＂ cauliflower sign＂ or ＂concertina pattern＂ in all of the 4 cases; CT images revealed a conglomeration of multiple small bowel loops in all 6 cases and the intestinal loops seemed to be encapsulated in a membranelike sac. Conclusion The imaging features of gastrointestinal barium meal and CT scan could suggest the diagnose of abdominal cocoon.
