Introduction: Thyroid cancer is the most common endocrine malignancy, and its incidence is increasing worldwide.

Objective: Our aim is to look at the prevalence of ultrasound features and FNA findings of nodules in patients operated on for thyroid cancer in our hospital.

Material and methods: Cross-sectional observational study of patients operated on for thyroid cancer at the Regional University Hospital between 2018-2021, we collected data on the ultrasound characteristics of the nodules and their classification according to the ultrasound risk scales: ATA and ACR-TIRADS. The analysis has been carried out using the JAMOVI program.

Results: 88 patients were included: 60 women and 28 men, mean age: 50.8 years (range 14-86 years), mean TSH 2.47 (SD 2.98), mean diameter of nodules: 25.8mm (SD 15.5), 87.1% are solid and 12.9% solid-cystic, 30.6% have microcalcifications and are ill-defined, borders are irregular in 39.5%, higher than wide in 14.1%. According to the ACR-TIRADS classification: II:1.2%, III:17.6%, IV:28.2% and V:47.1%, according to ATA classification: very low suspicion:1.2%, low suspicion:23.5%, intermediate suspicion:28.2% and high suspicion:47.1%. There is concordance between both echographic risk scales in 77 of the 85 patients (statistically significant correlation P< 0.05).

Conclusions: Both the ACR TI-RADS and the ATA risk stratification systems provide a clinically feasible thyroid malignant risk classification, with high thyroid nodule malignant risk diagnostic efficacy.
