Abstract

Situs inversus totalis (SIT) is a rare congenital condition in which the viscera are transposed as a mirror of normal physiologic arrangement. We describe a rare case of lingual thyroid associated with SIT. A 64-year-old female who was diagnosed with SIT, visited our clinic due to pharyngeal foreign body sensation. Physical examination revealed a 2.5x2.5x2.0 cm sized, pinkish, round mass in the base of the tongue. Computed tomography suggested the diagnosis of lingual thyroid. She has been on regular follow up with levothyroxine therapy. To our best knowledge, this is the first case of lingual thyroid (LT) associated with SIT. The literature is reviewed and clinical features about LT and SIT are presented.
