Evaluation of the Role of Fine Needle Aspiration Cytology in the Diagnosis of Follicular Patterned Lesions of Thyroid

Aim: The study aimed to evaluate the role of Fine Needle Aspiration Cytology (FNAC) in follicular patterned lesions of thyroid. Materials and methods: A prospective study was done in 30 cases in which FNAC showed follicular patterned lesions. Histopathological correlation was done wherever possible. Result: Out of 30 cases of follicular patterned lesions 17 cases were reported as follicular neoplasm, 12 cases were reported as adenomatous goiter and one case was reported as follicular variant of papillary carcinoma of thyroid in FNAC. Based on the FNAC diagnosis, surgery was done and histopathological correlation was available in nine cases. Conclusion: FNAC is quite accurate in follicular patterned lesions of thyroid with a sensitivity of 70.6%, specificity of 100% and diagnostic accuracy of 80%.
