Inverted colonic diverticulum mimicking a pedonculated polyp

Abstract

Colonoscopy plays an important role in colorectal cancer prevention because precancerous polyps can be detected and resected during the same exam, both adenomatous polyps and diverticular disease are common in people over 40 years old, and they frequently coexist, We reported a case of a 45-year-old women with no significant medical history presented for screening colonoscopy, endoscopic exams reveled a polypoid formation in the descending colon, with a peduncle of approximately 2 cm in length mimicking a pedonculated polyp diagnosed as an inverted colonic diverticulum and an endoscopic resection was avoided. The possibility of finding an inverted diverticulum mimicking colonic polyp during colonoscopy must be considered carefully for correct diagnosis and avoid dangerous procedures such as endoscopic polypectomy.
