Pneumonia is a rare complication of chickenpox in children and occurs in one-fifth of adults. The X-Ray may show multiple small round calcific lung lesions.

There are no significant chest x-ray findings observed in chickenpox. However, the following chest x-ray findings may be present in patients with varicella pneumonia:

• 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. ^{_Radiology_Reference_Article_|_Radiopaedia.org-1|[1]}
