The many faces of Meckel's diverticulum and its complications

Abstract

Meckel's diverticulum is the most frequent congenital malformation of the gastrointestinal tract, occurring in 2% of the general population. Meckel's diverticulum is usually asymptomatic and found incidentally. However, the lifetime risk of complications is 4-40%. In this essay, we describe the clinical and imaging findings in 12 cases of Meckel's diverticula with complications over a 5-year period, which were confirmed pathologically. The major complications of Meckel's diverticulum include gastrointestinal bleeding, bowel obstruction, perforation and inflammation. Small bowel follow-through (SBFT), computed tomography (CT) including CT enterography and RI scintigraphy can be used to show typical imaging features of Meckel's diverticulum and its complications. Knowledge of the clinical and radiologic findings of Meckel's diverticulum can aid in the early and accurate diagnosis of this anomaly and its complications.
