The radiological features of Histoplasma pericarditis.

The radiographic features of pericarditis due to Histoplasma capsulatum are described in 5 children. This diagnosis is suggested when enlargement of the cardiac silhouette is associated with pneumonia, parenchymal nodules or adenopathy. These findings are particularly significant if the patient lives or has lived in an area which is endemic for histoplasmosis. While pleural effusion is rare in primary histoplasmosis, it is frequently present in patients with histoplasma pericarditis.
