EU-TIRADS-Based Omission of Fine-Needle Aspiration and Cytology from Thyroid Nodules Overlooks a Substantial Number of Follicular Thyroid Cancers

Figure 2

The importance of timely diagnosis of follicular thyroid cancer. (a) An EU-TIRADS score 3 nodule (arrows) with a maximum diameter of 12 mm. According to EU-TIRADS, FNA is not indicated, and the diagnosis would have been missed. Final histology was minimally invasive follicular cancer restricted to the thyroid. (b) A 28 mm follicular cancer (arrows) metastasizing to the lungs. The patient was first examined in another hospital 12 years earlier. At that time, the diameter of the nodule was 14 mm, and FNA was not performed because of the absence of suspicious ultrasound characteristics.
