Bacterial Tracheitis

  • Etiology: Purulent infection of trachea where plaques form along tracheal walls, multimicrobial but often Staphlococcus aureus or Streptococcus, primarily bacterial or bacterial suprainfection post viral, plaques can occlude airway
  • Imaging: glottic + subglottic process, subglottic narrowing, loss of definition of trachea, membranes / plaques in trachea
  • Clinical: older and more ill than those with croup
