Answer

Perform chest radiography if pulmonary symptoms are present. Typical findings are bilateral patchy nodular or cavitary opacities (15% are cavitary) with an upper lobe predominance.

Normal chest radiographic findings with a single positive culture suggest that the organism is a contaminant or a transient colonizer and is not clinically significant. However, in the presence of chronic persistent pulmonary symptoms or repeatedly positive culture results, additional testing may be necessary.
