Ultrasound is the imaging modality for the initial assessment of thyroid nodules. There are well-established ultrasound findings that differentiate benign and malignant thyroid nodules and there are several classification systems, which categorize thyroid nodules according to the risk of cancer. Of the many classification systems that have been described, Thyroid Imaging Reporting and Data System (TIRADS) described by Kwak et al. is a relatively simple system which can be easily adopted and used in regular practice to facilitate the decision-making process regarding the need to perform fine-needle aspiration cytology (FNAC) for suspicious cases. The aim of the article is to assist in recognizing typical sonographic patterns of benign, suspicious and malignant nodules based on TIRADS criteria and thus helping in planning for further management of the patient. In this pictorial review, a complete series of sonographic images along with their pathological correlation is presented to illustrate benign and malignant features of thyroid nodules according to the TIRADS classification.
