Spontaneously resolving idiopathic bilateral chylothorax

Chylothorax is a relatively rare clinical entity caused by injury or obstruction of the thoracic duct or its tributaries leading to accumulation of chyle in the pleural cavity. It is characterized by a high concentration of neutral fat and fatty acids in the pleural fluid. Bilateral chylothorax is even more unusual, the commonest etiology being malignancy and trauma. However, we report a case of idiopathic bilateral chylothorax which resolved with medical management.
