CTICasesNecrotizing Staphylococcus aureus Pneumonia
Imaging findings
CT chest shows rapid development of bilateral consolidations and multiple thin-walled cavities (pneumatoceles) within a background of acute respiratory distress. The patient was co-infected with Influenza A and Staphylococcus aureus.
Key takeaways
Secondary bacterial pneumonia (especially Staphylococcus aureus) is a well-documented, severe complication of Influenza A. It typically presents as a necrotizing pneumonia with cavitation and the formation of multiple thin-walled pneumatoceles, carrying high morbidity.
