EU-TIRADS 1, normal

Normal: no nodules present in the thyroid.

CondutaNo fine-needle aspiration is indicated because category 1 means that no thyroid nodule is present to sample.

RiscoNot applicable (no nodule).

EU-TIRADS 2, benign

Benign: purely cystic nodule, or an entirely spongiform nodule.

CondutaFNA not indicated (except for therapeutic purposes).

RiscoMalignancy risk close to 0%.

EU-TIRADS 3, low risk

Low risk: oval shape, smooth margins, isoechoic or hyperechoic, with no high-risk feature.

CondutaFNA if the nodule is larger than 20 mm.

RiscoMalignancy risk 2-4%.

EU-TIRADS 4, intermediate risk

Intermediate risk: oval shape, smooth margins, mildly hypoechoic, with no high-risk feature.

CondutaFNA if the nodule is larger than 15 mm.

RiscoMalignancy risk 6-17%.

5 de 5

EU-TIRADS 5, high risk

High risk: nodule with at least one high-risk feature - non-oval (irregular) shape, irregular margins, microcalcifications, or marked hypoechogenicity.

CondutaFNA if the nodule is larger than 10 mm.

RiscoMalignancy risk 26-87%.
