RESUMEN
Acute lymphoblastic leukemia (ALL) is the most common malignancy of children.Gastrointestinal complications can occur during treatment of these children due to disease infiltration in gut or treatment-related toxicity. Intestinal obstruction is one of these complications and this occurs mostly due to constipation and impacted stool. Intussusception is a very rare entity in children with ALL. Left sided colo-colic intussusception is even rarer. Most of the intussusceptions are ileo-colic and are associated with a lead point. We present a case of left sided colo-colic intussusception in an 8-year-old child with ALL. There was no lead point or leukemic infiltrate in the resected part of the intussusception. Our child had typhlitis leading to intussusception which is a very rare occurrence. Awareness regarding this complication with ALL is important for prompt diagnosis and treatment.
