Overview

Loeffler syndrome must be differentiated from other diseases that cause pulmonary eosinophilia, such as Churg-Strauss, drug and toxin-induced eosinophilic lung diseases, other helminthic and fungal infection related eosinophilic lung diseases, and nonhelminthic infections such as Coccidioidomycosis, and Mycobacterium tuberculosis, .

Differentiating Loeffler syndrome from other pulmonary eosinophilia syndromes on the basis of etiology.
