Intussusception of the cecum with calcified fecaliths

We treated a patient with a complete invagination of the cecum that contained two large laminated calcified fecaliths. Colonofiberscopy showed a dimpling submucosal tumor that was palpated as a bony hard tumor at laparotomy. This finding suggested that the fecaliths caused intussusception of the cecum and that such an intussusception should be suspected when a bony hard, dimpling submucosal tumor is found in the cecum. To our knowledge, this is the first reported case of a cecal invagination accompanied by calcified fecaliths without an appendical intussusception.
