Case contributed by Imad Awwad
Diagnosis probable

Presentation

Fever and dyspnea for the last 10 days.

Patient Data

Age: 80 years
Gender: Male

Bilateral consolidation with peripheral distribution and lower lobes preference gives the "reversed bat wings" appearance. Ground glass patchy opacities with interlobular septal thickening are also present. Small pleural effusion.

Case Discussion

The patient had an elevated eosinophil count in peripheral blood (6%). Combined with the reversed bat wings appearance, this makes the diagnosis of eosinophilic pneumonia very probable.
