title: Cecorectal intussusception induced by a cecal hamartoma.
abstract: Cecorectal intussusception, a variant form of intussusception, occurs when the cecum enters through the entire course of colon and reaches to the rectum. This condition is rare but often associated with a pathologic lead point. Here, we report a 13-year-old boy, featuring insidious abdominal discomfort and constipation for 1 month, who developed cecorectal intussusception. Before surgical intervention, multi-detector row computed tomography with reconstructed images demonstrated the route of cecorectal intussusception and identified a cecal fat-containing tumor as the lead point. The patient received surgical reduction with resection of the cecal tumor. Final pathological diagnosis was a hamartoma of the cecum. The relevant literature pertaining to this condition is reviewed, and the possible pathophysiology of the condition discussed.
