We herein describe the case of a 50-year-old man who presented with intermittent right lower quadrant abdominal pain which he had been experiencing since December 2013. The pain symptoms gradually worsended, and he was therefore hospitalized on May 2014. Abdominal CT showed the cecum invaginated into the ascending colon as leading point of the ileocecal valve . Emergency colonoscopy revealed the same status as observed in the CT findings. We attempted to reposition the invagination during colonoscopy by releaseing gradually over the air pressure. Colonoscopy performed on the 13th hospitalization day revealed the presence of an ulcer on the cecal diverticulum. As stated above, we speculated that cecal diverticulitis had thus caused the cecal invagination in this case. It is extremely rare that an invagination case is treated conservatively and thereafter shows a good recovery.
