Neck swelling after thyroidectomy: not always a haematoma.

We present a case of a patient who returned with a neck swelling 6 days following thyroidectomy and central neck compartment lymphadenectomy for suspected thyroid carcinoma. The initial clinical suspicion pointed to a haematoma, but a needle aspiration showed chyle. Chyle leak is a rare complication of thyroid surgery. In the described case, this was successfully managed conservatively with repeated aspirations and a low-fat diet. We discuss the aetiology, presentation and management of this complication. 2015 BMJ Publishing Group Ltd.
