Successful Management of Rare Idiopathic Chylopericardium Mimicking as Pyopericardium in an Infant

Chylopericardium is a rare entity which is characterised by accumulation of chyle in pericardial sac. The absence of an underlying etiology is defined as idiopathic chylopericardium. In pediatric age group chylopericardium can resemble pyopericardium. If suspected the diagnosis of chylopericardium could be easily made with fluid analysis. The management of idiopathic chylopericardium could be conservative or surgical, but there are no guidelines. We report a case of idiopathic chylopericardium initially diagnosed as pyopericardium and its successful management.
