Prenatally, the umbilicus is of paramount importance, providing the gateway between the mother and the fetus. As the fetus becomes increasingly autonomous at the end of the second month of fetal life, the connections (vitelline, urachal) diminish in significance and involute. Disturbances in this process can result in a wide variety of abnormalities, ranging from relatively minor defects identified at birth (umbilical granulation tissue) to life-threatening complications quiescent until late adulthood (urachal carcinoma). This section will review the 'state of the art' in evaluation and management of these umbilical and related abnormalities.
Infantile umbilical hernia is a clinically benign condition that resolves spontaneously in majority of cases without surgical treatment. Complications like rupture are exceptionally rare. This report presents a previously healthy 8-month old infant who had spontaneous umbilical hernia rupture with evisceration and identifies the clinical features associated with this complication by including a review of previously reported cases.
The vitelline or omphalomesenteric duct malformations constitute a rare group and are seen in only 2% of people. The malformations can take the form of a patent duct, a cyst, a fistula, or a sinus. They may or may not be symptomatic depending on the type of malformation. We present ultrasonographic features of a patent omphalomesenteric duct remnant in a 3-week-old boy who presented to our hospital with a non-healing umbilical lesion. Ultrasound can prove beneficial in the work-up of such cases.
