Abstract: Studies of medical consequences following the Chernobyl accident have shown that there is a need to solve specific tasks in how to use ultrasound: performing mass ultrasonic screening for early recognition of pathology; following up patients for early nosologic diagnosis, and conducting differentiated diagnosis between benignand malignant pathology of the thyroid. The purpose of the study was to explore ultrasonic visualisation of thyroid carcinoma for its early diagnosis.We have studied particularities of thyroid cancer (ultrasonic pictures) in 97 patients before surgical removal (female-male ratio 1.6:1). The ultrasonic picture of thyroid carcinoma can be categorised into two forms: nodular and diffuse. The nodular variant can be divided into nodes with limited spread (which have either regular or rather regular outlines) and nodes with a vast spread (with an irregular outline). More frequently the tumour is visualised as a hypoechogenic node. However, isoechogenic character of the node might indicate either the dissemination or multifocal growth of a tumour within the thyroid gland. Isoechogenic character of visualised cervical lymph nodes is likely to indicate the presence of malignancy in the thyroid. Thyroid carcinoma is frequently followed by metastases in the area of regional lymph nodes. Location of the node next to the thyroid capsule might cause extracapsular invasion of the tumour (pT4). Signs of «node ageing» cystic degeneration and calcification are rarely visible.
