Point-of-Care Ultrasound for Undifferentiated Abdominal Pain in a Pediatric Patient: A Proposed Algorithm

Abdominal pain is a common presentation in the pediatric emergency department and may pose a diagnostic challenge to the physician. 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.
