[Ultrasonic and scintigraphic changes of the euthyroid goiter in the course of drug therapy. I]

We studied the ultrasonographic and scintigraphic changes of thyroid gland of 81 goitreous patients before and after treatment with exsiccated thyroid. About 57.8% of goitres showed a reduction of size, while no change was observed in 30% of patients; a further growth of the gland was seen in 13% of patients in spite of therapy. A difference between ultrasonography and scintigraphy in evaluating after-treatment follow-up was also noted, and a different response of nodules and diffuse hyperplasia to treatment assessed.
