We have established that nodal formations are detected with a frequency of 34.1% of cases. An analysis of the prevalence of nodal pathology of thyroid gland depending on sex showed that female sex (20.5%) was in the lead for this indicator. The heterogeneity of the echostructure of thyroid tissue in nodal lesion was determined by hypo- or isoechogenic formations having a rounded or oval shape. Their dimensions ranged from a few millimeters to a few centimeters or more. Along the periphery, the nodal formations were surrounded by a well-defined hypoechogenic rim. In the structure of thyroid nodal pathology, single nodes were more common (62.2%). The frequency of multiple node detection was 37.8%. More often, lobar nodal lesion was detected (71%), mainly left-sided localization. With a single nodal lesion, single nodes up to 1 cm in size were noted in 64.3% of observations and 1 cm in size or more in 35.7% of observations. Multi -node pathology was dominated by multiple nodes larger than 1 cm, accounting for 53.0% of cases; no des up to 1 cm in size in combination with nodes 1 cm or more were observed in 17.6% of cases. The specific gravity of multiple nodes up to 1 cm in size was noted in 29.4% of observations. According to ultrasonic morphometry and the calculation method, we determined the thyroid volume both in single and in multi-node lesion. Single and multi-node thyroid lesions in most cases were not accompanied by an goiterogenic effect. Conclusion. Thyroid nodes were identified in 34.1% of the surveyed residents of Dolon village of East Kazakhstan region. In the structure of thyroid node pathology, the detection percentage of single and multiple nodes was 62.2% and 37.8%, respectively. The dominant localization of thyroid nodes was lobar - 71% (frequency of nodal lesion of the right lobe 33.3%, left lobe 37.7%). The frequency of detection of clinically significant thyroid nodes (1 cm or more) in a single nodal gland lesion was 35.7%, in a multi -nodal lesion - 70.6%. Nodal lesion in most cases was not accompanied by signs of goiter transformation of the organ. The value of the thyroid volume was 10,191 ± 1, 192cm 3 , reaching with a single nodal lesion 9,898 ± 1, 690cm 3 , and with a multi-nodal lesion - 10,675 ± 2, 278cm 3 . |
