Giant colonic diverticulum.

Background: Over 100 giant colonic diverticuli have been recorded in the literature to date. The magnetic resonance imaging (MRI) and pathophysiology of their aetiology have rarely been described.

Aim: To report a giant colonic diverticulum along with the MRI of this clinical entity.

Results: An 87 year old female presented with symptoms of tenesmus, urgency and alteration in bowel habit. A type I giant colonic diverticulum was diagnosed and a segmental colonic surgical resection was performed. The plain abdominal radiograph, barium enema and MRI, along with classification and management options are presented.

Conclusion: Giant colonic diverticuli are rare surgical curiosities that may be successfully treated with either primary segmental or extended colonic resection.
