BackgroundIntussusception is an unusual disorder among the complications of diverticula in adults. This study aimed to report intussusception due to an inverted colonic diverticulum. Such a large inverted colonic diverticulum has rarely been reported.Case presentationA 62-year-old Chinese woman presented to the First Hospital of Jilin University with abdominal pain, vomiting, and bloody stool. Preoperative computed tomography imaging indicated intussusception. The intraoperative diagnosis was consistent with postoperative pathology. Our patient was diagnosed as having an inverted colonic diverticulum near the ileocecal valve with intussusception and intestinal necrosis.ConclusionAlthough inverted colonic diverticulum is extremely rare, it should also be considered among the causative factors of intussusception.
