Abstract Objective: To investigate the diagnostic value of ultrasonographic features for papillary thyroid carcinoma(PTC) with different sizes. Methods: The ultrasonographic features of 341 PTC nodules in 279 patients which were confirmed by surgery and pathology were analyzed retrospectively. According to the largest tumor diameter, the nodules were divided into three groups: ≤1 cm group, >1~2 cm group and >2 cm group. The distribution of irregular shape, hypoechoic, anteroposterior to transverse diameter ratio≥1(A/T≥1) and microcalcifications in different groups were evaluated. Results: Among the 341 PTCs, there were 209 cases, 87 cases and 45 cases in ≤1 cm group, >1~2 cm group and >2 cm group respectively, and in which irregular, hypoechoic, A/T≥1 and microcalcifications were 84%(175/209), 80%(168/209), 56%(118/209), 46%(97/209); 71%(62/87), 73%(64/87), 42%(37/87), 66%(58/87); 69%(31/45), 35%(16/45), 13%(6/45), 73%(33/45). PTCs with irregular shape and microcalcifications in ≤1 cm group and >1~2 cm groups, ≤1 cm groups and >2 cm group had statistically significant difference; hypoechoic PTCs in ≤1 cm group and >2 cm group, >1~2 cm group and >2 cm group had statistically significant difference; PTCs with A/T≥1 in ≤1 cm group and >1~2 cm groups, ≤1 cm groups and >2 cm group, >1~2 cm group and >2 cm group had statistically significant difference. Conclusions: There is a significant difference in the distribution of various ultrasonographic features of PTC with different sizes. Correct identification of these differences will help to improve the accuracy of pre-operative diagnosis of PTC and reduce the incidence of misdiagnosis.
