FNAC and Its Utility in Solitary Thyroid Nodule and Its Correlation with Histopathological Examination

Discrete swelling in one lobe of thyroid gland with no palpable abnormality elsewhere is termed as a solitary thyroid nodule. FNAC is the investigation of choice in solitary nodule for selection of surgical cases due to compliance, simple and quick to perform. The aim of this study was to evaluate the utility of FNAC in solitary thyroid nodule with the relation of histopathological findings. In this prospective observational study fifty (50) patients of solitary thyroid nodule without multinodular goitre, diffuse goitre, dominant nodule and clinically hypothyroidism or hyperthyroidism were included from admitted patients of different institutes of Comilla both private and government Medical College Hospital, Bangladesh. All patients were clinically examined and investigation findings from thyroid scan, ultrasonogram of thyroid gland, FNAC of thyroid nodule, histopathological report of excised thyroid were collected and posted into data collection sheet. The data were analysed with simple statistical table. The result showed that among 50 patients 41 patients were detected as benign nodule after FNAC which is about 82%. Malignant lesions were 12% (6 patients) and 6% (3 patients) of the case was indeterminate as because the specimen were unsatisfactory. The sensitivity, specificity, and accuracy of FNAC diagnosis in relation to histopathological findings were 100%, 83.33% and 97.87%. So FNAC is sensitive and accurate method for evaluation of solitary thyroid nodules.
