We present a case report of a 70-year-old male patient with a giant goitre. The patient experienced recurrent episodes of syncope/fainting, when he turned his head towards to the right, and he experienced discomfort when lying on his back. A CT scan showed compression of the right carotid artery and carotid sinus from a thyroid mass. After a mass of 1,473 g of thyroid tissue had been removed by a right thyroid lobectomy, the patient experienced no further episodes of syncope. It is well known, that giant goitres can bring a wide range of symptoms including compression of arteries, veins, nerves and related structures on the neck and in the thorax.
