• Abdominal Radiographs: Showed loss of normal hepatic silhouette and a soft-tissue mass in the cranial abdomen.
• Abdominal Ultrasound: Identified a heterogeneous, vascular hepatic or splenic mass with regions of cavitation and hypoechoic fluid pockets consistent with hemorrhage.
  Free anechoic fluid in the abdomen indicated hemoabdomen.
• Abdominocentesis Yielded non-clotting, hemorrhagic fluid confirming intra-abdominal bleeding
