Intestinal malrotation

Case contributed by Dr Bruno Di Muzio


Incidental finding, Patient under evaluation for nephrolithiasis.

Patient Data

Age: 48-year-old
Gender: Female

CT Abdomen and pelvis

CT images showing a twisted and enlarged superior mesenteric vein around the superior mesentric artery, as well as a downward pattern of the second portion of the duodenum, being involved in the twisted mesenteric structures. The cecum is in a subhepatic position. There is a calculus in the left renal pelvis. 

Case Discussion

This case illustrates the whirl sign (the swirling appearance of the mesentery and superior mesenteric vein around the superior mesenteric artery) in a patient with intestinal malrotation. There are no signs of bowel obstruction, though. The whirl sing is usually seen in the context of a midgut volvulus, which is a possible complication of the intestinal malrotation. 

Unfortunately no further clinical data is available on how the case was managed.
