We report a rare case of spontaneous regression of omphalomesenteric remnant after birth. Unlike previously reported cases, no surgery was required. The omphalomesenteric duct sometimes persists at birth. Its regression after birth, however, is extremely rare. A neonate passed a bloody stool 3 minutes after birth. Meckel's scan detected slight technetium-99 m uptake around the umbilicus. Sonographic examination detected a luminal structure connected to the small bowel, which gradually regressed, however, and was no longer visible by the 52nd day after birth. Careful follow-up is required after occurrence of bloody stool and intestinal obstruction from Meckel's diverticulum.
