Thyroid gland is a very rare location of non-epithelial tumors (less than 1% of all thyroid tumors) and particularly schwannomas. Only 19 cases have been published in English literature until today. Approximately 25% of schwannomas occur in the head and neck region, most of them in relation to peripheral nerves and to cervical sympathetic chain. We present a case with clinical and sonographic features of a benign thyroid nodule. The diagnosis of schwannoma was established after definitive histopathologic evaluation. With this article we intend to review clinical, radiological and pathological changes associated with this tumor, emphasizing the difficulty in making a preoperative diagnosis.
