Acute eosinophilic pneumonia

Case contributed by Dr Yair Glick


Fever, productive cough, shortness of breath for past two weeks. Unresponsive to antibiotic treatment. Asthmatic, smoker.

Patient Data

Age: 18 years
Gender: Male

Basal-predominant patchy alveolar opacities superimposed on reticular opacities.


Follow-up radiograph 2 days later, following steroid treatment

Complete resolution of alveolar opacities, with presistence of reticular opacities.

Case Discussion

The patient had been on empiric antibiotic treatment prescribed at the health maintenance clinic for a presumptive diagnosis of bacterial pneumonia.

Complete blood count on hospital admission was remarkable for eosinophilia (10,000/µL, with the normal range being 0-400/µL). The patient was treated with ceftriaxone, clarithromycin, and prednisone, with a complete resolution of symptoms within a single day.

The symptomatology, prononuced eosinophilia, chest radiograph findings, and prompt resolution of symptoms after treatment which involved steroids, all point to acute eosinophilic pneumonia.
