Imaging manifestations of Meckel's diverticulum

Abstract

Objective: Meckel's diverticulum is the most common congenital anomaly of the gastrointestinal tract, found in 2% of the population in autopsy studies. Most patients remain asymptomatic during their lifetime. Complications of Meckel's diverticulum are reported to occur in approximately 4-40% of patients and include inflammation (diverticulitis), hemorrhage, intussusception, small-bowel obstruction, stone formation, and neoplasm. The purpose of this article is to familiarize the radiologist with the current imaging of Meckel's diverticulum and its presenting complications. The spectrum of diagnostic findings on various imaging techniques will be reviewed.

Conclusion: Meckel's diverticulum and its complications are a serious health problem. Familiarity of the radiologist with the appearance of this pathologic entity enables an accurate diagnosis in emergent settings.
