Recurrent chylothorax associated with sarcoidosis.

Spontaneous chylothorax, an uncommon manifestation of pulmonary disease, has been described in association with infectious and inflammatory conditions involving the chest, thoracic trauma, and thoracic neoplasms. Isolated chylothorax is a rare manifestation of sarcoidosis and is usually associated with the presence of mediastinal and hilar adenopathy causing obstruction of the thoracic duct. We report a case of recurrent spontaneous chylothorax in a patient with parenchymal sarcoidosis without hilar or mediastinal adenopathy.
