Introduction: Intussusception, which is common in pediatric patients but rare in adults with leukemia, usually presents with an intralumenal lesion as a lead point in adults.
Case report: We herein report the case of a 38-year-old female who developed right lower quadrant abdominal pain and fever on day 16 of chemotherapy. Abdominal computed tomography showed ileocecal intussusception. The patient underwent surgery, and the definitive pathological diagnosis was typhlitis leading to intussusception. Albeit very rare in adults, typhlitis-induced intussusception should be suspected in those with leukemia presenting with abdominal pain.
Keywords: Acute lymphoblastic leukemia; Intussusception; Typhlitis.
