Inverted Meckel's Diverticulum in Adult Presented with Iron Deficiency Anemia and Caused Intussusception But Not Obstruction: Case Report

Meckel's diverticulum (MD) is the most common congenital anomaly of the gastrointestinal tract that seen in the 1-2% of the population. However it is often asymptomatic it may present with hemorrhage, intestinal obstruction, intussusceptions or inflammation. Inverted MD, where MD literally inverts on itself, is an uncommon condition underlying pathophysiology has not been explained fully. It may cause obstruction or occult bleeding due to the intussusception. We presented a case of 52-year-old male which inverted MD causing ileoileal intussusception without any symptoms of obstruction or abdominal pain detected while investigating the etiology of iron deficiency anemia. Inverted Meckel's diverticulum should be suspected in adult patients with iron deficiency anemia even if abdominal symptoms does not accompany.
