We report a case of a fetal omphalocele in which the internal structure of the hernia sac was imaged in detail by magnetic resonance (MR) imaging. The hernia sac consisted of amnion, Wharton jelly, and externally, peritoneum. The umbilical vascular channels (2 arteries, one vein) were surrounded by Wharton jelly. Use of MR imaging facilitates a more accurate evaluation of fetal omphalocele with regard to hernial sac, intestinal structure, and differential diagnosis.
