Answer

In S aureus pneumonia, lobar enlargement with bulging of interlobular fissures can be seen in severe cases. Abscesses, cavitations (with air-fluid levels), and pneumatoceles are not uncommon and 30-50% of patients develop pleural effusions, half of which are empyemas. Note that cavitation and associated pleural effusions are also observed in cases of anaerobic infections, gram-negative infections, and tuberculosis.
