Figure 1 A 55-year-old woman with systemic lupus erythematosus, who had been followed up regularly for 7 years, visited our hospital complaining of chronic abdominal fullness, constipation, and stringy stools. She had a history of a total hysterectomy for uterine prolapse at the age of 38. At colonoscopy we found a 3-cm-long tubular structure, with normal-appearing mucosa, in the cecum; histopathological examination showed colonic mucosa with mild inflammation. A diagnosis of inverted appendix was made.

Figure 2 Virtual colonoscopy performed immediately 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.
