Fine Needle Aspiration Cytology (FNAC) Findings of Thyroid Lesions In Correlation with Ultrasonographic (USG) Findings & Thyroid Function Tests (TFT)
Keywords:FNAC thyroid, USG thyroid, Thyroid function test, Thyroid lesions
Introduction: FNAC is helpful to distinguish between nonneoplastic and neoplastic lesions of thyroid. USG is easily accessible, noninvasive method for imaging various thyroid lesions. FNAC findings of thyroid lesions along with USG findings and TFT are helpful in making accurate diagnosis and management by correlation of it.
Aims & Objectives:
• To study the various cytological features of FNAC of thyroid and categorize according the Bethesda system for diagnosis
• Correlation of FNAC findings with USG findings of thyroid lesions
• To access TFT of various thyroid lesions in correlation with FNAC findings.
Materials and Method: The present study included total 100 patients with thyroid swelling underwent TFT, USG and FNAC. FNAC was done without local anaesthesia and smears were made. Smears were stained by PAP’s stain, H&E stain and MGG stain. Microscopy was done to study cytological features of various thyroid lesions and reporting was done according to TBSRTC.
Results: In present study, total 100 patients underwent for TFT, USG and FNAC of thyroid gland. Maximum number of patients was in 31 to 40 yrs age-group and majority were females. According to FNAC, 93 patient had nonneoplastic lesions and 7 patient had neoplastic lesions. Colloid goiter was predominant lesion among Nonneoplastic lesion and Follicular neoplasm was predominant lesion among Neoplastic lesion . On evaluation of TFT, majority patients were in Euthyroid state. Various USG parameters were studied following standard reporting categories and according to USG findings, diagnoses were divided into nonneoplastic lesions(96%) and neoplastic lesions(4%). USG diagnosis of thyroid lesions were correlated with FNAC.
Conclusion: FNAC is important diagnostic modality for Thyroid lesions. FNAC findings of thyroid lesions along with USG findings and TFT are helpful in making accurate diagnosis and management by correlation of it.
