Meckel's diverticulum Imaging: In and Out.

Meckels diverticulum (MD) is the commonest among the omphalomesenteric duct anomaly spectrum with an overall incidence of 2-3% . It is a true diverticulum arising on the antimesenteric side of distal ileum approximately 2 feet from the ileocecal junction. Heterotopic gastric and pancreatic mucosa are commonly found within the diverticulum predisposing to bleeding and inflammation. Complications are more common in male and the type of complication differs based on the age of occurrence and include hemorrhage, inflammation, obstruction, ischemia and tumor formation. Due to overlapping clinical presentation, imaging plays a vital role in the diagnosis of complications. Commonly used imaging modalities include Ultrasonography (USG), Computed Tomography (CT) and Nuclear medicine. This pictorial essay aims at providing the spectrum of Meckels diverticulum related complications, key embyrological concepts, role of imaging in the diagnosis and current guidelines on the management of incidentally picked MD.
