[Ultrasonographic pattern and levels of thyrotropin and antithyroid antibodies in patients with recurrent neutral goiter after subtotal thyroidectomy]. 
The study comprised 65 women (mean age 43 years) with the recurrent goiter after subtotal strumectomy.  All patients were subjected to ultrasonographic examination using a sonograph Sonoline LM (Siemens) with 7.5 MHz head.  The study was aimed at: 1) assessment of etiology of goiter recurrence, 2) assessment of changes in the thyroid parenchyma, 3) detection of the occurrence of heterogeneous structures, such as nodules, cysts and calcifications.  It was found that goiter recurrence appeared mainly in the patients subjected to surgery because of neutral nodular goiter.  The observed changes in the thyroid stump, such as heterogeneous structure of parenchyma, generalized cyst-like spaces and nodular structures mainly of mixed type or of solid, normo-echogenic or hyper-echogenic type, were associated with high levels of THS and the presence of antithyroid antibodies in blood serum.  In patients with evidently high TSH levels and positive with respect to occurrence of antithyroid antibodies, the nodular structures were more numerous and of larger size.  In can be concluded that ultrasonography provides a valuable noninvasive tool for the evaluation of morphological structure of the recurrent goiter.
