Although most abdominal pain is benign, the presence of abdominal pain may represent a surgical emergency. We present an atypical presentation of perforated appendicitis in a child with 2 weeks of abdominal pain, in whom point-of-care ultrasound expedited diagnosis and patient disposition. We then recommend a diagnostic approach for using point-of-care ultrasound in a pediatric patient with undifferentiated abdominal pain. Copyright © 2020 Wolters Kluwer Health, Inc.
