A 90-year-old woman was admitted to our hospital because of dizziness, without any remarkable abdominal symptoms. Severe anemia was found and thus gastrointestinal investigations were performed. CT and ultrasonography showed the specific multiplex layer configuration at the anal side of the descending colon. Colonoscopy showed a round tumor occupying the lumen and a consecutive gastrografin enema showed a crab-claw-like area without filling in the descending colon. Intussusception of the colon was diagnosed and partial resection of the descending colon was performed, but without relief of intussusception. The tumor was histologically diagnosed as mucinous adenocarcinoma. By various factors, incomplete fixation between the retroperitoneum and the descending colon might result in the present condition.
一名90岁女性因头晕入院，无明显腹部症状。检查发现严重贫血，因此进行了胃肠道检查。CT和超声检查显示降结肠肛门侧有特定的多层结构。结肠镜检查显示一个圆形肿瘤占据肠腔，随后的钡剂灌肠显示降结肠有一个蟹爪样无造影剂充盈区。诊断为结肠套叠，行降结肠部分切除术，但套叠未缓解。肿瘤组织学诊断为黏液腺癌。综合各种因素，腹膜后与降结肠之间固定不完全可能导致了目前的情况。
