Teenager with abdominal pain and increased WBC and CRP

CT of splenic volvulus
Axial CT with contrast of the upper abdomen in the portal venous phase (above left) shows the spleen is absent from the left upper quadrant and is instead seen in the midline of the pelvis (above right). Coronal (below left) and sagittal (below right) CT in the delayed phase show the spleen to be in the midline of the pelvis above the bladder. The splenic vascular pedicle had a whirlpool appearance (not provided).

The diagnosis was splenic volvulus.
