ABSTRACT
We report here a case of Hurthle cell adenoma with eggshell calcification that presented as a thyroid incidentaloma on ultrasonography (US) in a 58-year-old woman. The mass was hypoechoic with continuous eggshell calcification and intranodular vascularity as seen on gray-scale and power Doppler (PD) US. Hurthle cell adenoma should be considered in the differential diagnosis of a thyroid nodule with eggshell calcification.
