Summary
Fine needle aspiration with ultrasonography guide (PAEAFT) is a highly accurate diagnostic tool for thyroid nodules. This study analyzed 139 PAEAFT cases, finding follicular neoplasms most common, predominantly in females.
Area of Science:
- Endocrinology
- Cytopathology
- Oncology
Background:
- Fine needle aspiration (PAAF) is crucial for thyroid nodule diagnosis.
- Ultrasonography guidance enhances the sensitivity and specificity of PAAF.
- PAEAFT offers improved diagnostic accuracy for thyroid lesions.
Purpose of the Study:
- To evaluate the diagnostic efficacy of fine needle aspiration with ultrasonography guide (PAEAFT).
- To analyze the cytologic diagnoses and patient demographics from PAEAFT procedures.
- To assess the distribution of thyroid nodule types and prevalence in relation to sex and age.
Main Methods:
- Retrospective analysis of 139 PAEAFT cases.
- Cytologic material processed using conventional and thin smear techniques.
- Staining with Hematoxylin and eosin (H&E), Diff-Quik, and Papanicolaou stains.
- Analysis of cytologic diagnoses, nodule characteristics, patient sex, and age.
Main Results:
- Follicular neoplasms were the most common diagnosis (57.57%), particularly low-grade.
- Multinodular Goiter (21.58%) and Papillary Carcinoma (4.32%) were also significant findings.
- The study population was predominantly female (93.52%).
- Hürthle cell tumors and Hashimoto's thyroiditis were diagnosed in 2.87% of cases each.
Conclusions:
- PAEAFT is a sensitive and specific method for diagnosing thyroid nodules.
- The study highlights the high prevalence of follicular neoplasms and the female predominance in thyroid pathology.
- The findings support the use of PAEAFT in the diagnostic algorithm for thyroid nodules.
