| Purpose: The purpose of this study is to identify clinical and imaging parameters
that can be used in differentiation of benign versus malignancy of preoperative FNA
diagnosis of Bethesda system IV nodules.
Materials and Methods: We analyzed clinical, ultrasonographic, and CT findings of
28 thyroid nodules with Bethesda system IV cytology on FNA, which were proven as
follicular or Hu ¨rthle cell neoplasms on surgical pathology.
Results: No statistically significant differences according to age, sex, and ultrasonographic
parameters, including echogenicity, margin, calcification, shape, cystic component,
and degree of vascularity and enhancement on CT were observed between
benign and malignant follicular neoplasms. Only the lesion size was significantly different
(p<0.05).
Conclusion: The size of follicular neoplasm is predictive of malignancy. If a thyroid
nodule with the Bethesda IV cytology is larger than 24.5 mm, there will be a greater
probability of malignancy. |
