Abstract
Introduction: Persistent omphalomesenteric duct anomalies are very rare the world over. These anomalies are in a spectrum and present in various forms, ranging from the infamous Meckel's diverticulum to a fibrous non-patent connection between the umbilicus and the distal ileum, to a patent connection between the umbilicus and the intestine, the patent omphalomesenteric duct.
Case Report: A two-month-old female child who was born with a membrane-covered umbilical mass which after sometime, became two swellings with intestinal epithelial covering and fistulous openings. At surgical exploration, she was discovered to have a patent omphalomesenteric duct which opened into the appendix, as well as intestinal malrotation abnormality.
Conclusion: The occurrence of patent omphalomesenteric duct opening into the vermiform appendix is a rare occurrence and there should be high index of suspicion when there is failure of healing of the umbilical stump and there is discharge of intestinal contents via the umbilicus.

Keywords: Appendix, Carcinoid tumor, Embryonic vitelline duct, Intestinal malrotation
