Patient Data

Age: 18 years
Gender: Male

PA upright: Basal-predominant patchy alveolar opacities superimposed on reticular opacities.

Follow-up radiograph 2 days later, following steroid treatment


PA upright: Complete resolution of alveolar opacities, with the persistence 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.
