Varicella Pneumonia
-
Findings: multiple, small punctate calcifications
throughout both lungs. Miliary TB classically does not heal with
calcification of the granulomas. The lesions in miliary TB are also
usually much smaller than these lesions. Mitral hemosiderosis occurs
primarily at the lungs bases and is, of course, associated with
mitral valve disease which this patient does not have. Staph
pneumonia characteristically gives airspace disease with an
effusion.
-
Occurs most often over the age of 19 rather than in
childhood
-
Patchy, diffuse air space consolidation
-
Tendency to coalesce near hila
-
Widespread nodules can occur (30%)
-
Tiny calcifications remain in 2% (DDX is
histoplasmosis, alveolar microlithiasis)
-
11% mortality rate
