An 18-day-old female neonate showing abdominal distention was transferred to our hospital. Since X-ray images showed abdominal free air, we performed emergent laparotomy and also performed direct closure of the perforation site located at the end of the ileum. At 1 month after discharge, ileus was recognized; however, she recovered with conservative therapy. At 7 months after birth, she presented with bloody stool and anemia. Contrast-enhanced CT showed enhanced areas at the end of the ileum. We confirmed that bleeding was responsible for the enhancement of these areas; therefore, we performed laparotomy. Since a hemangioma was recognized on the ileum wall and mesentery, we resected the ileocecal portion. The pathological diagnosis was infantile intestinal hemangioma. She was discharged 10 days after the operation. There have been no signs of recurrence or progressive anemia. Infantile intestinal hemangioma shows rapid proliferation from one week after birth, peaking at 1 year of age. In this case, the intestinal perforation in the neonatal period was consistent with the beginning of the proliferation phase. Bloody stool was recognized in the peak proliferation period. We presume that both events were caused by infantile intestinal hemangioma.
