Presentation
Incidental finding, Patient under evaluation for nephrolithiasis.
Patient Data
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.
