Objective:

To report a case of varicella pneumonia in an adult and highlight the importance of prompt treatment for improving patient outcomes.

Approach:

Key Findings:

• Generalized vesicular rash, fever, hypoxia, and pulmonary infiltrates are characteristic of varicella pneumonia in adults.
• Imaging findings supported the diagnosis, showing bilateral micronodules and ground-glass opacities, with the lungs being the most commonly affected organ.
• Early initiation of intravenous acyclovir within 24 hours of rash onset is associated with faster recovery and reduced risk of respiratory failure and mortality.

Interpretation:

Varicella pneumonia is a serious condition that requires prompt recognition and treatment, particularly in adults without prior immunity.

Limitations:

• Single-case design limits generalizability.
• Lack of comparative data does not allow estimation of treatment effects.
• Further research is needed to validate findings and treatment recommendations.

Conclusion:

Intravenous antiviral therapy is recommended for varicella pneumonia, and early treatment is crucial for improving outcomes.
