Legionella pneumonia causing multiple cavitating pulmonary nodules in a 7-month-old infant.

The Legionella bacillus is a relatively common cause of pneumonia in adults, especially those with malignant tumors, transplanted organs, on chronic lung disease. The characteristic radiographic pattern is segmental air-space consolidation, which progresses to more widespread consolidation. We report a case of Legionella pneumonia in a 7month-old infant who had multiple pulmonary nodules, some undergoing cavitation, which eventually resolved.
