No pleural effusion or pneumothorax.

Normal size and appearance of the cardiothymic silhouette.


  • The hallmark of viral bronchiolitis in young children (< 2) is hyperinflation, which is usually accompanied by peribronchial thickening and scattered subsegmental atelectasis
  • As a general rule, there is hyperinflation if the lungs are expanded below the 6th anterior or 9th posterior rib on the frontal view. There should be flattening of the hemidiaphragms on both views
