Abstract Objective: To investigate the correlation between preoperative sonographic features of follicular thyroid carcinoma(FTC) and its pathological subtypes. Methods: The preoperative sonographic features of 35 lesions in 35 patients and their pathological subtypes were analyzed. Benign FTC were defined as showing none of the accepted ultrasonography criteria for malignancy, and malignant FTC were defined as showing at least one of the accepted ultrasonography criteria for malignancy. Clinicopathologic factors and sonographic features were compared between benign FTC and malignant FTC. Based on the degree of invasiveness from pathology, FTCs were divided into minimally invasive FTC(MI-FTC) and widely invasive FTC(WI-FTC). Sonographic features were compared between MI-FTC and WI-FTC. Results: Compared with B-FTC, a significantly higher prevalence of WI-FTC, an irregular shape, an ill-defined margin, and calcification were showed in malignant FTC(P＜0.001, P=0.045, P＜0.001, P=0.015, respectively). Compared with MI-FTC, an ill-defined margin, and irregular halo ring were more frequent in WI-FTC (P＜0.001, P=0.025, respectively). Conclusions: It can be confirmed that there is a significant correlation of preoperative sonographic features of follicular thyroid carcinoma and its pathological subtypes.
