Question 3#

Persistence of the vitelline duct can lead to which of the following?

A. Colonic diverticulum
B. Urachal cyst
C. Umbilical cord hernia
D. Omphalomesenteric duct cyst

Correct Answer is D


During the third trimester of pregnancy, the vitelline duct regresses. Persistence of the vitelline duct remnant on the ileal border results in a Meckel diverticulum. Complete failure of the vitelline duct to regress results in a vitelline duct fistula which is associated with drainage of small intestinal contents from the umbilicus. If both the intestinal and umbilical ends of the vitelline duct regress into fibrous cords, a central vitelline duct (omphalomesenteric duct) cyst may occur.
