Abstract:
The omphalomesentric duct (OMD) is the communication between the developing embryonic disc and the yolk
sac. It is the last point to close after separation of intestine from the yolk sac. If the development is halted at any
time during the final closure, then the communication between the intestine and yolk sac may not be
obliterated. Hence in approximately 1-4% of infants, a remnant is retained. The persistence of remnants of the
OMD within the umbilical cord can be an incidental finding. Intestinal polyp of umbilical cord, a variant of OMD
is an extremely rare abnormality. It may indicate the presence of Meckel's diverticulum, may be associated with
the atresia of small intestine or other anomalies. Therefore its early recognition can decrease the risk of
developing life threatening complications.
