Angiodysplasia and Meckel's diverticulum: a congenital association?

Five patients under the age of 21 years are described in whom a Meckel's diverticulum was found in association with angiodysplasia of the caecum or ascending colon. Angiodysplasia has only been observed previously in patients over the age of 35 years and its demonstration in 5 young patients with Meckel's diverticulum points not only to an association between the two disorders, but suggests that angiodysplasia may have a congenital aetiology.
