A case of ingested water beads diagnosed with point-of-care ultrasound.

A previously healthy 12-month-old girl presented to the emergency department with vomiting of water beads (superabsorbent polymer). The girl did not have clinical or radiographic signs of residual foreign bodies or intestinal obstruction. Point-of-care ultrasound showed well-demarcated, round, and hypoechoic materials in the stomach and first part of the duodenum, indicating ingested beads.
