Incomplete 90° intestinal rotation in a clockwise direction results in complete common mesentery being placed in a mirror image to and with a similar appearance to complete common mesentery. This rotation places the colon in the right half of the abdominal cavity and the small intestine in the left half of the abdominal cavity. We report the case of a 19-year-old patient with a history of cerebral palsy secondary to meningitis who presented with melaena and inflammatory anaemia. CT enterography was performed which showed regular, non-stenosing circumferential wall thickening of the sigmoid colon and rectosigmoid junction compatible with Crohn's disease, which was confirmed by pathophysiology. It also revealed transposition of the colon to the right hemi-abdomen and the small intestine to the left hemi-abdomen, the caecum to the right iliac fossa, and the third portion of the duodenum to the left of the mesenteric vessels.
Complete common mesentery in the mirror image is an anomaly of intestinal rotation, placing the colon in the right half of the abdomen and the small intestine in the left half of the abdomen.It can be asymptomatic and discovered incidentally during assessment for other conditions.
90°顺时针方向的不完全肠旋转导致完全共同肠系膜呈镜像排列且外观与完全共同肠系膜相似。这种旋转使结肠位于腹腔右半侧，小肠位于腹腔左半侧。我们报告一例19岁患者，有因脑膜炎继发脑瘫的病史，表现为黑便和炎症性贫血。进行了CT小肠造影，显示乙状结肠和直肠乙状结肠交界处有规则的、非狭窄性的环形壁增厚，符合克罗恩病，经病理生理学证实。还显示结肠转位至右半腹，小肠转位至左半腹，盲肠位于右髂窝，十二指肠第三段位于肠系膜血管左侧。
镜像的完全共同肠系膜是肠旋转异常，使结肠位于腹部右半侧，小肠位于腹部左半侧。它可能无症状，在评估其他疾病时偶然发现。
