Tension pneumothorax with evolving cysts in an infant

Abstract

Secondary air leaks and cavity formation as sequelae of respiratory syncytial virus (RSV) are exceedingly rare. • Cavitary changes in the lung may develop secondary to RSV with mucus plugs and air trapping. • RSV is a frequent cause of pneumonitis in infants that rarely requires surgical intervention, but it is important to recognize the possibility of such complications, which may occur even as the primary infection is resolving.
