キーワード : Adenomatous goiter, Ultrasonography

Ultrasonographic findings of 59 patients diagnosed as adenomatous goiter pathologically were evaluated about the following points; whether nodule(s) were multiple or solitary, cystic or solid, with calcifications or not, and with diffuse enlargement of the thyroid gland or not. Comparing the ultrasonographic diagnosis based on these findings with pathological diagnosis, the following conclusions were drawn;
1. The cases showing typical ultrasonographic findings such as multiple cystic nodules and/or diffuse enlargement of the thyroid were diagnosed correctly by ultrasonography.
2. In 63.6% of patients diagnosed falsely by ultrasonography, macroscopic findings were atypical of adenomatous goiter.
3. Ultrasonographically, lesions seemed to localize in one lobe in 54.2% of patients.
4. Ultrasonographically, multiple nodules were demonstrated in 47.4% of patients, while solitary nodule in 44.1%.
5. Calcifications were observed in 20.3% of patients ultrasonographically.
6. Ultrasonography could not reveal the concomitant presence of small carcinomas.
