Abstract:

Objective   To investigate ultrasonographic features of Hashimoto′s thyroiditis(HT) with papillary thyroid carcinoma(PTC) for improving the accuracy of diagnosis. Methods   130 HT patients with thyroid nodules(PTC or benign nodules) were selected. Ultrasonographic and clinicopathological features were analyzed. Results   Nodules of HT with PTC were usually characterized by irregular shape, ill-defined edge of the border, hypoechoic and heterogeneous echogenecity in the interior, and calcification. In addition, statistical analysis showed the shape and location of calcification had significant differences between benign and malignant nodules. Conclusions   HT with PTC has some ultrasonographic features, especially presenting with calcification and hypoechoic echogenecity in the interior of nodules. Ultrasound-guided fine-needle aspiration biopsy (US-FNAB) should be carried out for definite pathological diagnosis if necessary.
