Introduction: The management of patients with nodular goiter and thyroid neoplasms is one of the most important problems in modern thyroidology. There are several classifications based on thyroid ultrasound for selecting suspected malignant thyroid nodules. The Thyroid Imaging Reporting and Data System (TI-RADS) classification is an easy to apply for thyroid lesions, which might be helpful in clinical practice for the initial assessment of the thyroid lesion risk of malignancy.

Material and Methods: A retrospective study of all patients who underwent thyroid surgery at the ENT department of Tahar Sfar Hospital in Tunisia (n= 108) from January 2013 to December 2017. After surgery, histological results were correlated to the ultrasound findings reported.

Results: The mean age of our patients was 46 years. A clear predominance of women was found (94% of the cases). 17% of the cases were diagnosed with thyroid cancer and 83% of the cases with benign disease. Correlation of histological results with preoperative ultrasound reports showed an initial sensitivity of 95%, a specifity of 82% with positive and negative predictive values of 53% and 98%.

Conclusion: The TIRADS score is an interesting tool in the detection of malignant thyroid nodules, thus avoiding excessive surgical indications. The use of the TI-RADS scale would also allow for an adequate selection of patients amenable to fine needle aspiration of the nodule
