Appendiceal intussusception requiring ileocecectomy

Background: Intussusception of the appendix is a relatively rare condition with an estimated incidence of 0.01%. It can mimic several clinical conditions including acute appendicitis or be mistaken as a cecal polypoid lesion on radiological imaging making the diagnosis before or during surgery is very difficult. Case presentation: A 6-year-old female presented to our unit with complaining of colicky abdominal pain and repeated vomiting for 3 days with no history of constipation. Abdominal examination revealed mild right iliac fossa tenderness and mild abdominal distension. Abdominal ultrasound revealed subhepatic intussusception mass measuring about 3 × 4 cm suggesting underlying Meckel's diverticulum. Three trials of hydrostatic reduction under ultrasound guidance were failed. Abdominal exploration revealed appendiceal intussusception mimicking cecal mass with failed trial of reduction. Ileocecectomy done with primary ileocolic anastomosis. We discharged our patient on the seventh day postoperatively. Conclusions: We report a rare case of appendiceal intussusception that required ileocecectomy in young female child. appendiceal intussusception is very rare condition but it must be considered in children.
