Filarial pleural effusion without peripheral blood or pleural fluid eosinophilia

Abstract

Lymphatic filariasis is a tropical parasitic disease and is endemic in India. It is present in various forms but its manifestation as pleural effusion is rare. Here, we describe a case of 58-year-old male who presented with complaint of left side chest pain and breathlessness. He was investigated and diagnosed as a case of left side pleural effusion due to filariasis, with peripheral blood lymphocytosis but without peripheral blood or pleural fluid eosinophilia. Our case foregrounds that filariasis can present with peripheral blood lymphocytosis and without peripheral blood or pleural fluid eosinophilia.
