BACKGROUND
Small intestine duplication cysts (SIDCs) are rare congenital anatomical abnormalities of the digestive tract and a rare cause of hematochezia.
CASE PRESENTATION
We describe an adult female presented with recurrent hematochezia. The routine gastric endoscope and colonic endoscope showed no positive findings. Abdominal CT scan indicated intussusception due to the "doughnut" sign, but the patient had no typical symptoms. Two subsequent capsule endoscopes revealed a protruding lesion with bleeding in the distal ileum. Surgical resection was performed and revealed a case of SIDC measuring 6 * 2 cm located inside the ileum cavity. The patient remained symptom-free throughout a 7-year follow-up period.
CONCLUSION
SIDCs located inside the enteric cavity can easily be misdiagnosed as intussusception by routine radiologic examinations.
背景
小肠重复囊肿（SIDCs）是一种罕见的消化道先天性解剖异常，也是引起血便的罕见原因。
病例介绍
我们描述了一位成年女性反复出现血便的病例。常规胃镜和结肠镜检查未发现阳性结果。腹部 CT 扫描提示由于“甜甜圈”征而出现肠套叠，但患者没有典型的症状。随后进行的两次胶囊内镜检查显示在回肠末端有一个突出的带血病变。行手术切除后发现一例位于回肠腔内的 SIDC，大小为 6*2cm。患者在 7 年的随访期间无任何症状。
结论
位于肠腔内的 SIDCs 很容易被常规影像学检查误诊为肠套叠。
