Inverted Meckel's diverticulum: an entity simulating an ileal polyp.

A case of inverted Meckel's diverticulum is described. This presented as an ileal polyp in an individual with chronic unexplained iron deficiency anemia. Most prolapsed Meckel's diverticula occur acutely as intussusceptions with bowel obstruction and characteristically develop in childhood. This case therefore represents an unusual surgical problem in an older individual in which the diagnosis was clinically unexpected.
