Which is diagnostic for epiglottitis?

Explanation:
A lateral neck X-ray of the soft tissues is diagnostic because it directly shows the swollen epiglottis. On this view, the epiglottis appears enlarged and rounded, creating a characteristic “thumbprint” sign that confirms epiglottitis. Blood tests or throat swabs don’t visualize the epiglottis and can’t confirm the diagnosis; they may help rule out other infections but are not definitive. Signs and symptoms may suggest epiglottitis, but the radiographic finding provides the confirmatory evidence needed. In practice, securing the airway is the priority, with imaging supporting the diagnosis.
