Viral respiratory tract infection

Viral respiratory tract infection is a broad term given to pulmonary infection from various agents.

Pathology

They can be caused by a large number of viral agents. The list includes

RNA viruses
DNA viruses

Radiographic features

Plain radiograph / CT

Most common findings are including bilateral perihilar peribronchial thickening and interstitial infiltrates which particularly in children due to their small calibre airways this can result in several areas of atelectasis or air trapping. Sometimes air space consolidation and haemorrhage may also develop. Pleural effusion and specifically hilar lymphadenopathy and pneumothorax are uncommon findings. However, imaging findings alone are not sufficient for the definitive diagnosis of viral pneumonia and radiographic patterns can be variable dependant on virus as a well as host factors.
