  • Title: [Preoperative assessment of thyroid nodules in an endemic goiter region--possibilities and limitations].
    Author: Mikosch P, Gallowitsch HJ, Kresnik E, Lind P.

    Abstract:
    In iodine-sufficient areas any thyroid nodule has to be regarded as potentially malignant, whereas in iodine-deficient areas (endemic goiter areas) thyroid nodules, even multinodular goiter, are frequent. The majority of thyroid nodules in an endemic goiter area can be regarded as being most likely benign and thus not all patients with multinodular goiter have to undergo surgery. The major diagnostic aim and challenge is the selection for surgery of only those patients who suffer from mechanical obstruction due to large goiter and those who present with nodules suspicious of malignancy. Thus, for these cases the question of accurately excluding or verifying malignancy is essential for the patient and the specialist of nuclear medicine or endocrinology. A variety of investigations may be used for the preoperative evaluation of thyroid nodules, although currently sonography and fine-needle biopsy have to be regarded as the key investigations to clarify preoperatively the dignity of thyroid nodules. The article presents the indications and limitations of the different methods in use for the evaluation of thyroid malignancy. The authors present a diagnostic algorithm for the preoperative evaluation of thyroid malignancy with special respect to problems occurring in a(n) (former) endemic goiter area.
