Eosinophilic Pleural Effusion Due To Artemisnin: A Case Report

INTRODUCTION: Drug induced eosinophilic pleural effusion (EPE) is well documented in literature. EPE is not a disease rather an interesting laboratory finding, defined as >10% eosinophils in pleural fluid, exclusive of erythrocytes. Pleural fluid eosinophilia may be associated with blood eosinophilia e.g. Loeffler syndrome, Churg Strauss syndrome etc. Conversly EPE can also occur without blood eosinophilia e.g. Pulmonary Infarction, Pneumonia or Trauma. We report a case of bilateral EPE secondary to Artemisnin with no peripheral eosinophilia.
