Two Cases of Intussusception Caused by Malignant Pathological Lead Points in Older Children

Abstract

The incidence of intussusception with pathological lead points in children increases with age. We report two cases of childhood intussusception caused by malignant pathological lead points. [Case 1] A 13-year-old boy was admitted with a one-year history of abdominal pain. Computed tomography demonstrated multiple small bowel tumors and ileocolic intussusception, and tumor resection was performed. Histopathological examination revealed the pathological lead point to be myeloid sarcoma. [Case 2] A 13-year-old boy was admitted with a two-month history of abdominal pain. Computed tomography demonstrated ileocolic intussusception and a small bowel tumor, and we performed tumor resection by laparotomy. Histopathological examination revealed the pathological lead point to be Burkitt lymphoma. Intussusception in older children and recurrent intussusception were reported to be associated with lead points. When lead points cannot be detected by ultrasonography or other imaging modalities, exploratory laparotomy should be considered.
