Abstract

ABSTRACT-All but the earliest viral pneumonia pathologic changes have their counterpart on the chest roentgenograms. Viral pneumonias often have a significant alveolar component. Lobular, segmental, and lobar opacifications are common in bacterial pneumonia but may also be anticipated from viral infection. Radiologic distinction between the two etiologies is not possible when these patterns are present. The viral pneumonia nodular pattern due to peribronchiolar inflammatory foci is infrequent in the bacterial pneumonias. It is possible that viral pneumonia may produce some cases of chronic interstitial fibrosis now classed as idiopathic. INDEX TERMS: Chickenpox - Influenza.
