title: Colonoscopic diagnosis of appendiceal intussusception in a patient with intermittent abdominal pain: a case report.
abstract: Intussusception of the appendix is a rare condition. Most cases are diagnosed during operation of the patients suspected to have appendicitis. In this report we present a seventy one year-old man with a history of periumbilical intermittent abdominal pain for several months. None of the paraclinical tests were useful for determining the diagnosis. Colonoscopy performed during the last episode of abdominal pain revealed the prolapsed appendix in the cecum and the patient was sent to the operating room. Macroscopic appearance of the appendix was normal and microscopic examination revealed follicular hyperplasia and acute focal appendicitis. Appendiceal intussusception should be considered in differential diagnosis of intermittent abdominal pain and colonoscopic diagnosis could be very important to avoid dangerous or unnecessary decision making.
