Summary
Embryonic omphalomesenteric duct remnants can cause rare adult diseases. This case highlights the unusual simultaneous presence of multiple remnants, including Meckel
Area of Science:
- Embryology
- Gastroenterology
- Surgical Pathology
Background:
- The omphalomesenteric duct connects the embryonic yolk sac to the midgut.
- Failure of its involution leads to various remnants like Meckel's diverticulum.
- These remnants are found in 2% of the population but rarely cause adult disease.

Appendicitis
Appendicitis is an acute inflammatory condition of the vermiform appendix, most commonly caused by obstruction of its lumen. The appendix is a narrow, blind-ended pouch that extends from the cecum, making it particularly prone to obstruction. Causes include fecaliths, lymphoid hyperplasia (often after viral infections), parasites, tumors, or foreign bodies. This obstruction initiates a cascade of pathological changes.Luminal Obstruction and Early InflammationAfter obstruction, normal mucosal...
Diverticular Disease of the Colon
Diverticular disease involves the formation of diverticula—small sac-like outpouchings of the colonic wall—and their complications. It most commonly affects the sigmoid colon due to higher intraluminal pressure and structural vulnerability. It results from structural weakness and increased pressure in the colon, producing pseudodiverticula that may remain silent or progress to inflammation and serious complications.Structure of DiverticulaIn diverticulosis, these outpouchings are...
