Neck Point-of-Care Ultrasound for the Identification of Tongue-Base Cysts in Infants With Stridor: A Case Series.

Tongue-base cysts, which are occasionally categorized as vallecular cysts, are a rare yet potentially life-threatening cause of stridor in pediatric patients. Studies reporting the use of point-of-care ultrasound (POCUS) to identify tongue-base cysts are lacking. We present the case series of four infants in whom tongue-base cysts were detected using neck POCUS.
