Eosinophilic Lung Diseases of Determined Origin

Once the diagnosis of eosinophilic pneumonia has been established, potential causes must be thoroughly investigated since identification of a cause may lead to effective therapeutic measures. When present, nonrespiratory manifestations contribute to the diagnosis of the possible clinical entity, especially for Churg-Strauss syndrome (CSS). 

Parasite infestation (mostly by helminths) (10) represents the main cause of eosinophilic pneumonia in the world. The diagnosis may be difficult and requires appropriate serologies and repeated search of parasites in the feces. 

Central bronchiectasis (inner two-thirds of chest CT field) 

Immediate cutaneous reactivity to Aspergillus species or A. fiimigatus 

Serum precipitating antibodies to A. fumigatus Criteria for the diagnosis of ABPA-seropositive
