Objective: Fine needle aspiration (FNA) biopsy and ultrasonography are the methods used to evaluate thyroid nodules and to predict malignancy together with the clinical characteristics of nodules. It is important to know false positive and false negative incidences of FNA especially in the case of follicular neoplasia or indeterminate lesions such as atypia of undetermined significance (AUS) to decide whether surgery is necessary or not. The aim of this retrospective study was to evaluate ultrasonographic characteristics of histopathologically verified malignant thyroid nodules and histopathologic correlation of cytologically indeterminate lesions with histopathologic diagnosis.
