Echinococcal Cyst Rupture in a 3-Year-Old Boy With a Minor Abdominal Trauma Identified by a Point-of-Care Ultrasound E-Fast Examination: A Case Report and Literature Review.

Point-of-care ultrasound is now widely used in adult and pediatric emergency departments as part of the rapid evaluation and treatment of patients in urgent care settings. It has been shown to be a powerful tool to aid in decision making in both trauma and acute medical situations. We describe a case of a 3-year-old boy who presented with abdominal pain and fever after a minor abdominal trauma, highlighting the use of point-of-care ultrasound to arrive at the diagnosis of a ruptured echinococcal cyst.
