The spleen is the intra-abdominal organ most often injured as a result of blunt trauma.

The spleen is the most vascular organ, for this reason, a splenic injury is potentially life-threatening.

On arterial phase, CT images bright white “blush” or amorphous collection within a hypodense injured solid organ indicates active bleeding. When lacerations extend through the organ capsule, hemoperitoneum results;  if the capsule is intact, a subcapsular hematoma may be demonstrated.
