Epiglottitis

  • Etiology: classically due to Haemophilus influenzae type b in 2-5 year old, now due to Staphylococcus / Streptococcus in 10-11 year old, swollen areyepiglottic folds cause airway obstruction
  • Imaging: supraglottic process with swollen epiglottis + thickened aryepiglottic folds, subglottic trachea normal, thumb sign = imprint of swollen epiglottis on airway
  • Complications: can obstruct airway, need to have someone who can manage obstructed airway with patient at all times
  • Clinical: symptoms are sore throat / drooling / high grade fever, appear toxic with stridor / dysphagia / restless / respiratory distress / head tilted forward to keep airway open, symptoms are less severe in older patients today
