Pulmonary infiltrates with eosinophilia; Loeffler syndrome
Simple pulmonary eosinophilia is inflammation of the lungs associated with an increase in eosinophils, a type of white blood cell.
Most cases of simple pulmonary eosinophilia are due to an allergic reaction, either from a drug, such as sulfonamide, or infection from a fungus or parasite, including Ascaris lumbricoides.
