History: 38 yo female with h/o proctocolectomy for UC and acute abdominal pain.
Solution: Wandering spleen is a rare congenital anomaly that renders the spleen more susceptible to complete organ infarction. The spleen is attached by a long vascular pedicle, but without the usual fixating ligaments to the diaphragm, colon, left kidney, and lateral abdominal wall. This allows torsion of the freely mobile spleen around its vascular pedicle, which can occlude the blood supply and lead to infarction. In this case, the laxity of the supporting structure for the spleen was likely post-surgical and in addition to the spleen, there was also small bowel involved in what was actually an internal hernia. The spleen and a portion of the small bowel herniated through a defect in the mesentery (once again, likely post-surgical) and this resulted in a closed loop bowel obstruction and an infarcted, torsed spleen.
