Abstract

Introduction
Appendicocecal intussusception is an uncommon condition which must be differentiated from other types of invagination due to different therapeutic approaches and its ultrasound findings are outspread and imperfectly presented in literature. We present a case with specific sonographic signs as well as review of related articles.
Case Presentation
A 3.5 year-old girl with intermittent crampy abdominal pain from one month ago that was recently exaggerated was associated with nausea and vomiting. She had specific sign of appendicocecal intussusception. Due to unsuccessful hydrostatic reduction, surgical intervention and appendectomy was performed.
Conclusion
The absence of clinical symptoms and ultrasound findings of small intestine obstruction and invagination target (transverse diameter less than 20 mm) adjacent to terminal ileum loop containing hypoechoic Peyer's patches can help differentiate appendicocecal invagination from the other types of invagination.
