Abstract
• We describe four patients who presented with a lingual thyroid condition (three females and one male, aged between 7 and 22 years). Only the male patient was symptomatic with mild dysphagia and hemoptysis. The diagnosis was suspected in three patients, and was confirmed by iodine 123 or 131 scanning in all patients and by a computed tomographic scan in the one patient studied. The patient with dysphagia received a 10-mCi therapeutic dose of iodine 131 before thyroxine replacement was started. The diagnosis and management of lingual thyroid is discussed. All patients need lifelong thyroxine suppression. Unenhanced computed tomographic scans have a diagnostic appearance due to the iodine content of the ectopic thyroid tissue.
