To demonstrate types of gastrointestinal tract diverticula To discuss common and rare complications of gastrointestinal diverticula To review common imaging features of diverticula and diverticular complications

A diverticulum is defined an outpouching of a hollow organ. The entirety of the gastrointestinal tract can be affected by varying numbers and types of diverticula. These diverticula, including upper tract and lower tract diverticula, can be sources of significant morbidity and even mortality through complications such as bleeding, infection, fistula formation, and perforation.
