Wandering Spleen with Tortion – A Case Report

A 16-year-old male presented with abdominal pain over 12 months, that had acutely worsened over the 5 days pre-presentation. Preliminary outpatient investigations revealed thrombocytopaenia 90(platelets per microliter), and a pelvic spleen on abdominal ultrasound. Contrast enhanced CT of the abdomen and pelvis in the portal venous phase confirmed a pelvic spleen with torsion of the splenic hilum. The spleen appeared hypoechoic on ultrasound. On CT, the spleen had heterogeneous enhancement with some irregularly shaped regions of hypoenhancement. There was a swirl (at least two complete turns) in the splenic vascular pedicle in the left abdomen. The splenic artery demonstrated some enhancement, but no enhancement of the splenic vein. The pancreatic tail was also involved in the torted vascular pedicle. No pancreatic duct dilation, and no infarct of pancreatic parenchyma were found. A small amount of free fluid around the spleen was found with no free gas. The portal vein enhanced normally. Lack of convincing enhancement of the splenic vein and heterogenous appearance of the spleen were suspicious for early splenic ischaemia. Laparotomy revealed an engorged twisted spleen around its pedicles. The spleen was identified in the pelvis with a torted vascular pedicle, which was subsequently detorted and manipulated back into the left upper quadrant (LUQ), with a pre-peritoneal space formed in the LUQ, the spleen was inserted into this pocket.
