Congenital hernia of the umbilical cord associated with extracelomic colonic atresia and perforation of gut in a newborn.

Congenital hernia of the umbilical cord (CHUC) is a rare congenital entity compared to more common post-natally occurring umbilical hernia. Although recognized as a distinct entity since 1920s, CHUC is often misdiagnosed as a small omphalocele, resulting in its underreporting. We present the first case report of CHUC associated with extracelomic colonic atresia, complicated by perinatal perforation in a newborn. We also discuss the differentiating features from other anterior abdominal wall defects such as omphalocele and gastroschisis including its embryogenesis.
