Epiglottitis: A 4-year-old child presented
with the sudden onset of fever, drooling, and stridor. A lateral
radiographic
view of the soft tissues of the neck demonstrates swollen anterior supraglottic
structures at the level of the hyoid bone consistent with epiglottitis.
This radiographic finding is also known as the thumb sign of epiglottis.
Epiglottitis is an acute inflammatory disease of the supraglottic structures
that is usually caused by
Haemophilus influencae type B, although
Staphylococcus aureus, beta-hemolytic
Streptococcus,
Moraxella
catarrhalis, and
Pneumococcus have been isolated. (L.S.)
