Journal Title: Sultan Qaboos University Medical Journal - Year 2014, Vol 14, Issue 4
Abstract
Te occurrence of ectopic lingual thyroid tissue was frst reported over 100 years ago. We report an unusual presentation of ectopic thyroid tissue occurring in the submental area. A 27-year-old female presented to the Sultan Qaboos University Hospital in Muscat, Oman, in October 2011 with an 8 x 6 cm mass which caused difculty in talking and a feeling of heaviness in the jaw. She was clinically and biochemically euthyroid upon presentation. Te clinical diagnosis was confrmed by a technetium-99m thyroid scan, magnetic resonance imaging and fne needle aspiration. A single dose of 976 megabecquerels of radioactive iodine-131 resulted in hypothyroidism after three months and the complete disappearance of the swelling and associated symptoms. At a two-year follow-up, the patient was healthy and continuing lifelong replacement therapy with thyroxine.
