RESUMO
Objective To investigate the ultrasonic imaging features of thyroid follicular adenoma for conducting the correct diagnosis and differentiation diagnosis.Methods The clinical and imaging data in 64 cases of pathologically proven thyroid follicular adenoma were analyzed on the maximal diameter of tumor,nodularity number,high and low echogenicity,peripheral halo,echo hom-ogeneity,calcifications,and so on.The misdiagnosis causes were investigated.Results The mass was mainly solid or cystic-solid mixed echo.The ultrasonic imaging features of thyroid follicular adenoma were non-peripheral halo or thin wall halo,hyperecho or isoecho,internal macrocalcifications and peripheral calcifications,homogeneous echo structure.Conclusion The ultrasonographic examination can provide the better diagnosis and differentiation diagnosis on thyroid follicular carcinoma.
