Clinical correlation, TIRADS and Bethesda systems with histopathological diagnosis of thyroid nodules. Case series

Abstract

Objective: The main purpose of the research was to conduct a study on the clinical correlation, TIRADS and Bethesda systems with histopathological diagnosis of thyroid nodules in post-thyroidectomy patients at Hospital Dr. Ricardo Baquero González. Period 2017-2022.

Methods: Non-experimental, retrospective, correlational, observational, retrospective design. The population and sample consisted of 30 patients. The clinical records of all patients with the presence of a thyroid nodule who underwent thyroidectomy were analyzed. To evaluate the homogeneity of the study sample the following variables were taken into account: clinical data, age, sex, nodule size, anatomopathological study, TIRADS and Bethesda systems.

Results: The study showed that the average age was 42.15 years, with a predominance of female 93.3% and male 6.7%. In the location of the nodules there was a predominance of multinodular goiter 60%, right nodule 26.67% and left nodule 13.33. The results show that 3 patients were classified as Tirads 4, of these, two were Tirads 4a, whose FNA was Bethesda II and Bethesda III. While the third was Tirads 4b, being categorized as Bethesda IV. All TIRADS <4 were 100% true negative and TIRADS ? 4 were true positive.

Conclusion: It is concluded that both the TIRADS system and the Bethesda system are equally effective in ruling out the presence of malignancy in thyroid nodules. The TIRADS system is slightly more sensitive than Bethesda in cases of thyroid nodules ? 3 cm.
