Radiographic features

CT

While being non specific, it has been described as a cause of a hemorrhagic pneumonia / infective cause of a localized pulmonary hemorrhage.

One of the more commonly described CT patterns have been patchy areas of ground glass opacities and consolidation. In immunocompetent patients these may have a more basal distribution while in immunocompromised patients they may be more diffusely distributed ³.

Centrilobular nodules maybe present in a small proportion of patients ^2-3.
