Bilateral chylothorax, as a complication of neck dissection, is very rare as evidenced by the 11 cases reported in the literature up to date. We present an additional case of bilateral chylothorax following a left radical neck dissection and concomitant chylous neck fistula. This case was successfully treated by chest drainage and total parenteral nutrition. Early diagnosis of chylothorax is urged due to the consequences on metabolism and respiratory conditions. Management by aspiration drainage is usually sufficient to control pleural effusions.
