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. Diagnosing an ICD can be confirmed by inspection and gentle eversion using the probe. In this case report, we present a patient who was found to have inverted colonic diverticulum as we highlight the importance of distinguishing it from colonic polyps in order to prevent severe complications.
