Ultrasonographic examination of the thyroid was carried out in 150 patients of mean age 37 +/- 11 years, including 100 patients with nontoxic parenchymal goiter and 50 patients with toxic parenchymal goiter associated with the Graves' disease. Ultrasonograph Siemens Sonoline LM with 7.5 MHz head was used in the study. The study was aimed at the evaluation of functional and morphological state of the thyroid in patients with nontoxic and toxic parenchymal goiter. In the case of nontoxic goiter, heterogeneous (100%) and normoechogenic (100%) structure of the parenchyma was visualized by ultrasonography. In toxic parenchymal goiter (Graves' disease), on the other hand, hypoechogenic (92%) and marginally pseudo-cystoid structure of parenchyma was observed. In this group of patients, high values of thyroid hormones (100%) were associated with high level of thyroid antibodies (92%). It can be concluded that ultrasonography is an useful tool for evaluation of functional and morphological state of the thyroid in patients with nontoxic and toxic parenchymal goiter. |
