Eosinophilic pleural effusions

Ioannis Kalomenidis et al. Curr Opin Pulm Med. 2003 Jul.

Abstract

Eosinophilic pleural effusions, defined as a pleural effusion that contains at least 10% eosinophils, may be caused by almost every condition that can cause pleural disease. Eosinophilic pleural effusion occurs most commonly during conditions associated with the presence of blood or air in the pleural space, infections, and malignancy. Drug-induced pleural effusions, pleural effusions accompanying pulmonary embolism, and benign asbestos pleural effusions are also among the common causes of eosinophilic pleural effusion. No etiology is found in as many as one third of patients. Because studies evaluating different diagnostic approaches with eosinophilic pleural effusions are lacking, the authors suggest that certain noninvasive and invasive diagnostic tools must be used based on the patient's clinical characteristics.
