Hemoperitoneum in the newborn is uncommon. When present, it usually results from traumatic injury to the liver,1 spleen,2,3 adrenal gland,4-8 an ovarian cyst,9 and, rarely, the pancreas, kidney, or intestine.6,10 Nontraumatic hemoperitoneum can occur in association with hemorrhagic disease of the newborn.10 We describe an infant with spontaneous hemoperitoneum from a ruptured neuroblastoma; to our knowledge, this is the first such patient to be described in the literature.
Report of a Case.—A 3,800-g, term female infant was born to a healthy 16-year-old girl (gravida 1) after an uncomplicated pregnancy, by a spontaneous nontraumatic vaginal delivery. Progressive abdominal distention, respiratory distress, and pallor developed in the infant shortly after delivery. Cardiorespiratory arrest occurred at 50 minutes of life. The infant was intubated and resuscitated. A periumbilical bluish discoloration was noted; paracentesis yielded 111 mL of blood, which had a hematocrit value of 29%.
