Abstract:
97 children with thyroid nodules found through screening programs in regions of White Russia (Belarus) affected by fallout from the Chernobyl disaster underwent thyroid ultrasound examination by one team at a central reference hospital. 46 of these children were operated on. 31 of these had thyroid carcinoma (30 papillary carcinoma, 1 follicular carcinoma), 9 adenoma, 3 nodular goitre, 2 thyroiditis and one colloid goitre. Sex distribution was equal in the carcinoma group while in all other groups females prevailed. In younger age groups (3-6 and 7-10 years) carcinomas were found more often than adenomas and cysts. A carcinoma was present most likely if there were a single nodule with a volume of more than 1.5 cm3, inhomogeneous echo structure, unclear, hypoechogenic margins, and enlarged regional lymph nodes.
