On the left a case of chronic eosinophilic pneumonia.
It was a patient with low-grade fever, progressive shortness of breath and an abnormal chest radiograph. 
There was a marked eosinophilia in the peripheral blood.
Like in COP we see patchy non-segmental consolidations in a subpleural distribution.
Chronic eosinophilic pneumonia is an idiopathic condition characterized by extensive filling of alveoli by an infiltrate consisting primarily of eosinophils. 
Chronic eosinophilic pneumonia is usually associated with an increased number of eosinophils in the peripheral blood and patients respond promptly to treatment with steroids. #Clinical #Radiology #CTChest #Eosinophilic #Pneumonia #EosinophilicPneumonia #RadiologyAssistant
