Umbilical evagination of the bladder with omphalocele minor

A neonate with umbilical evagination of the bladder (UEB) and omphalocele minor (OM) is reported. The findings in this case support the origin of the urachus from the upper end of the cloaca rather than the allantois. The frequent occurrence of OM with urachal anomalies, including UEB, suggests an embryological association between the two conditions.
