lntroduction: Appendiceal intussusception is a rare condition overall and even more uncommon in children. Case presentation: We report the case of an 11-year-old boy with no relevant medical history who was referred to our department for right lower quadrant (RLQ) abdominal pain and mildly elevated inflammatory markers. Ön examination, he exhibited RLQ tenderness with muscle guarding. Ultrasonography revealed an inflamed appendix, and surgery was therefore planned. During laparoscopy, a cecal mass was observed, with the appendix not identifiable. After conversion, an appendiceal intussusception was found with concomitant appendicitis. Manual reduction was performed, followed by appendectomy. The postoperative course was uneventful, and the patient made a full recovery. Discussion: The literature on this condition is limited to case reports. In the pediatric population, appendiceal intussusception is more common in boys. It is most often diagnosed intraoperatively, as its clinical features can mimic several other abdominal conditions in children. In rare cases, ultrasonography may reveal a target sign or pseudo-kidney sign. Recurrent ileocolic intussusception may suggest the appendix as a lead point. Laparoscopic appendectomy is the treatment of choice. Conclusion: Although ileocecal intussusception is relatively common in children, appendiceal intussusception is a rare entity and is therefore typically diagnosed intraoperatively. This report aims to raise awareness of this condition among radiologists and pediatric surgeons. Most cases are treated with appendectomy, with or without limited cecal resection.  Kulcsszavak: appendiceal intussusception; pediatric; appendectomy; case report
