We present a case of a follicular variant of papillary thyroid carcinoma (PTC) with an uncommon sonographic feature– hyperechoic rim. A 24-year old female was referred to our department for an incidentally discovered nodule in the left lobe of the thyroid gland with an accompanying neck lymphadenomegaly. Ultrasound revealed a 1-cm hypoechoic nodule with a hyperechoic periphery with peripheral vascularity. The cytological finding was suspicious for PTC. Histology confirmed the suspected diagnosis. Hyperechoic rim is an uncommon ultrasound feature of thyroid nodules. A potential association with follicular variant of PTC needs to be explored.
