Incomplete 90° clockwise intestinal rotation results in the colon being located on the right side of the abdomen and the small intestine on the left, leading to a mirror image of the common mesentery.
A case study of a 19-year-old patient with cerebral palsy showed symptoms of melaena and inflammatory anaemia, and CT scans indicated signs of Crohn's disease along with the mentioned anatomical anomaly.
This intestinal rotation anomaly can be asymptomatic and may be accidentally found during evaluations for other medical issues.
