Overview

Pneumonia, as a complication of chickenpox, rarely occurs in children, but occurs in about one-fifth of adults.

Varicella pneumonia is a type of viral pneumonia. It is a common cause of multiple small round calcific lung lesions.

Varicella-zoster virus (VZV) most commonly causes self-limited benign disease (chickenpox) in children. However, in adults it tends to cause significant complications such as VZV pneumonia.

Radiographic features

multiple 5-10 mm ill-defined nodules that may be confluent and fleeting small, round nodules usually resolve within a week after the disappearance of the skin lesions but may persist for months lesions can calcify and can persist as numerous, well-defined, randomly scattered, 2-3 mm dense calcifications.
