She had a his− tory of a total hysterectomy for uterine pro− lapse at the age of 38. At colonoscopy we found a 3−cm−long tubular structure, with normal−ap− pearing mucosa, in the cecum; histopathologi− cal examination showed colonic mucosa with mild inflammation. A diagnosi s of inverted ap− pendix was made. Figure 2 Virtual colonoscopy performed im− mediately after colonoscopy revealed a three− dimensional tubular structure, similar to that seen on colonoscopy. Inverted appendix should be considered in the differential diagnosis of cecal polyps. Unusualcasesandtechnicalnotes E139 U C T N This document was downloaded for personal use only.
