The “sentinel clot sign” is defined as the highest attenuation hematoma in proximity to an organ that is the primary source of bleeding in hemoperitoneum (Fig. 1a, b). The body attempts hemostasis by forming a clot at the site of injury; thus, the highest attenuation area is the nearest one to the source.
