Eductional Objective: On lateral neck x-ray, epiglottitis causes quickly escalating respiratory distress and an enlarged epiglottis ("thumbprint sign"). Haemophilus influenzae (ie, type b, nontypeable strains), a gram-negative coccobacillus that frequently produces concurrent bacteremia, is the most prevalent pathogen.
