Double Intussusceptions in a 20-Year-Old Lady Harboring a Tubulovillous Adenoma with High-Grade Dysplasia: A Case Report and Literature Review.

Underlying malignancy is a concern when intussusception is diagnosed in adults and the elderly. Management includes oncological resection of the intussusception. We report a case of a 20-year-old female patient who presented with signs of bowel obstruction. Computed tomography demonstrated double intussusceptions (ileo-cecal and transverse colo-colonic). During laparotomy, the mid-transverse intussusception reduced spontaneously while the other did not. Both intussusceptions were managed with oncological resection. The final pathology showed a tubulovillous adenoma with high-grade dysplasia. As a result, intussusception in adults should be investigated thoroughly to exclude malignant potential.
