CT of active splenic bleeding
Axial CT with contrast of the abdomen (above) shows a low-density laceration in the center of the spleen with a round focus of high intensity in the middle of it felt to represent active bleeding. Axial CT with contrast of the pelvis (below) shows a large amount of fluid in the pelvis posterior to the bladder.

The diagnosis was splenic trauma with active splenic bleeding and a large amount of hemoperitoneum.
