Bilateral chylothorax is a rare complication following neck dissection, with fewer than thirty cases being reported over the last century. A serious life-threatening condition mostly encountered during thoracic procedures and dissections. In our case, conservative management resulted in complete resolution. We report a case of a 4-year-old child who underwent deep neck dissection due to recurrent hemangioma. She developed bilateral chylothorax and a conservative approach led to complete resolution.
