Patient Data
Age: 25 years
Gender: Male
From the case:
Persistent descending mesocolon
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/137108/annotated_viewer_json?iframe=true\u0026lang=us"}
Oblique orientation of the descending colon, which seems to have failure of fusion of descending mesocolon to the lateral and posterior parietal peritoneum. It has caused medialisation of descending colon and small bowel loops seem to be located lateral to it. Features are consistent with persistent descending mesocolon.

Annotated images show the oblique orientation and medialisation of descending colon. Better seen in coronal view.
Case Discussion
Recognition of this rare normal anatomical variant is important although most of the cases are asymptomatic. However, it has clinical significance as it may cause intestinal obstruction, volvulus, intussusception as well as the internal hernia.
