Eosinophilic pleural effusion: a brief review of case reports in literature

Abstract

Eosinophilic pleural effusion is defined by an eosinophil count of more than 10 percent in the pleural fluid. Pleural irritation, trauma, and malignancy are common causes of eosinophilic pleural effusion. Drug reaction, infection, inflammation, pulmonary embolism, toxin, cirrhosis, and heart failure should be considered in the differential diagnosis. In this report the National Library of Medicine's Medline database was searched for case reports diagnosed with eosinophilic pleural effusion.
