Enteroliths of small bowel diverticula.

The formation of an enterolith within a diverticulum of the small bowel is a very rare occurrence. Complications of this include abscess formation, perforation and obstruction of the small bowel. We report four cases. One patient presented with intermittent pain relieved after calculus removal. One case was an incidental finding on barium follow through but presented with obstruction of the small bowel 3 years later. One patient presented with obstruction and perforation and a fourth patient showed several asymptomatic linear calculi in a single diverticulum.
