Point-of-care ultrasound for prompt diagnosis and treatment monitoring of acute epiglottitis.

A 72-year-old woman presented with a 1-day history of acute throat pain, hoarseness. On cervical ultrasonography (transverse view), the epiglottis was swollen with anterior-posterior diameter of 3.5 and 3.8 mm at right and left edges, respectively. Laryngeal endoscopy showed marked swelling of the epiglottis, and acute epiglottitis was diagnosed.
