Abstract:
During the neonatal period, pneumatosis intestinalis (PI) and portal venous gas (PVG) are pathognomonic of necrotizing enterocolitis (NEC). Rare cases of such findings evolving after abdominal trauma have been reported in adults and children, but none in premature infants. We report a case of a 3-week-old premature infant where both PI and PVG were found following a fall from a scale. The presence of these findings prior to the evolvement of clinical symptoms suggestive of NEC strongly supports a traumatic etiology.
