Case #14


Findings

  • Mild hyperinflation with bilateral peribronchial thickening
  • Hazy right basilar opacity
  • No pleural effusion or pneumothorax
  • Normal size and configuration of the cardiothymic silhouette


Diagnosis

  • Viral bronchiolitis

Sample Report

Mild hyperinflation with bilateral peribronchial thickening, which can be seen with viral bronchiolitis. Hazy right basilar opacity likely represents atelectasis though a developing pneumonia is not excluded.

No pleural effusion or pneumothorax.

Normal size and configuration of the cardiothymic silhouette.


Discussion

  • 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
