A Case of Inverted Colonic Diverticulum.

Inverted colonic diverticulum (ICD) is an infrequent finding on colonoscopy, often misdiagnosed as colonic polyps. Further endoscopic intervention, such as polypectomy or biopsy, may lead to colonic perforation. For that reason, the endoscopist should be aware of the possibility of detecting these lesions when performing a colonoscopy.
