Introduction: Thyroid nodules are generally benign, but the risk of malignancy ranges from
7% to 15%. Fine needle aspiration biopsy (FNAB) is frequently employed as a diagnostic
technique for thyroid malignancies due to its high accuracy, safety, and cost-effectiveness.
Aims: The aim of this study was to retrospectively evaluate the clinical and pathological data
of 165 patients who underwent thyroid FNAB at Isparta City Hospital.
Methods: The pathology results of patients diagnosed with a thyroid nodule and who
underwent thyroid FNAB in the interventional radiology department between January 2021
and February 2023 were retrospectively analyzed. The evaluation encompassed parameters
such as age, gender, localization, nodule size, nodule content, nodule echogenicity, nodule
heterogeneity, presence of calcification, number of nodules, and Bethesda classification.
Results: The average age of the 165 patients included in our study was 51.9 ± 12.7 years
(range: 17-82). Among the cases, 26 (15.8%) were male, and 139 (84.2%) were female.
Nodules were most frequently located in the right lobe. The average nodule size was
calculated as 21.3 ± 11.6 mm (range: 5-70). Of the nodules, 57% appeared hypoechoic,
40.6% appeared isoechoic, and 2.4% appeared hyperechoic. A cystic component was
observed in 59 cases, and calcification was present in 53 cases, with gross calcification noted
in 63.9% of them. Among the nodules, 46 (27.9%) were single, and 119 (72.1%) were
multiple. The borders of 73.9% of the nodules were regular. According to the Bethesda
classification, the most common group was benign, and the least common was malignant. In
the malignant group of men, nodules with hypoechoic and coarse calcification were observed
more frequently in the right lobe, showing a statistically significant relationship compared to
the benign group (p < 0.05).
Discussion and Conclusion: In our study, it was observed that the cases in which thyroid
FNAB was performed were consistent with the existing literature. Specifically, males,
hypoechoic nodules, and nodules containing coarse calcification should be subject to more
careful evaluation, and if deemed necessary, more than one sampling should be conducted.
