A 12-year-old child was admitted with a 6-month history of diarrhea, hematochezia, and weight loss. On physical examination, there was diffuse abdominal voluntary guarding without rebound tenderness. Laboratory test analysis revealed slight anemia (hemoglobin 10.2 g/dL, normal 12-16 g/dL), leukocytosis (23,000/ mm3, normal 4,500-11,000 mm3) with a left shift, and elevated C-reactive protein level (80 mg/dL, normal <5 g/L). Contrast-enhanced CT disclosed a thickened loop of terminal ileum and multiple pelvic fluid collections surrounding the ileocecal region (A).
