Eosinophilic pneumonia

What it means

The presence of eosinophils in lung tissue, generally as detected by tissue biopsy, with or without blood eosinophilia.

Pulmonary function testing usually reveals a restrictive process with reduced diffusion capacity for carbon monoxide. Laboratory tests typical include increased levels of eosinophils in the blood, a high erythrocyte sedimentation rate, iron deficiency anemia, and increased platelets.
