Chylothorax: A rare presentation of Constrictive Pericarditis.

A 22-year male patient presented as bilateral chylous pleural effusion. There was no evidence of intra-abdominal or pulmonary pathology. Further investigation proved constrictive pericarditis as the most likely etiology. Patient underwent pericardiectomy by a cardio thoracic surgeon. The diagnosis was of tuberculous pericarditis. Patient responded to antitubercular treatment. Constrictive pericarditis as a cause of chylothorax is rare but should be considered in the differential diagnosis of chylothorax.
