Infectious adult croup.

From January 1980 to December 1987, seven patients with acute inflammatory swelling of the subglottic space were treated. Their ages ranged from 25 to 73 years. Medical history and symptomatology are similar to those characteristic of laryngotracheobronchitis (croup) in the pediatric age groups (i.e., an antecedent common cold followed by a barking cough and varying symptoms of upper airway obstruction). Physical findings before and after treatment were confirmed and documented by anteroposterior radiographs of the neck. Three patients required airway intervention but there were no deaths. To our knowledge there are no previous reports in the English literature describing this entity in adults. The purpose of this presentation was to introduce physicians, in general, and otolaryngologists, in particular, to this potentially serious infection. Our limited experience suggests that the pathogenesis and management of croup in adults are very similar to those in children.
