Comparison of surgeon-performed ultrasound-guided fine needle aspiration cytology with histopathological diagnosis of thyroid nodules

OBJECTIVE: To assess the Solitary thyroid nodules by surgeon- performed ultrasound-guided FNAC and evaluate with the histopathological findings. METHODS: This study includes 100 Consecutive patients of a solitary thyroid nodule which were presented to the Outpatients Department of Surgery during the period of two years from September 2016 to August 2018. Exclusion criteria were patients with extra-thyroid swelling, diffuse goiter and multinodular goiter. All patients with a solitary thyroid nodule underwent Surgeon –performed ultrasound-guided FNAC in the department of Radiology. After thyroid surgery, thyroid specimens were sent for histopathology and evaluate with FNAC findings. RESULTS: The study included hundred patients with solitary thyroid nodule, 75(75%) female and 25 (25%) male with a ratio of F 3:1M. The age of the patients ranged from 15-75 years with a mean age of 35 years. The result of 100 cases of Surgeon –performed Ultrasound –guide FNAC of a solitary thyroid nodule were inconclusive in 10 cases (10%), Non-neoplastic in 60 cases (60%) and Neoplastic lesions in 30 cases (30%). After evaluation of findings from FNAC and histopathology, four cases with benign FNAC (adenomatous/colloid Goiter) turnout as neoplastic (papillary carcinoma) on histopathology and six cases with neoplastic FNAC (papillary carcinoma), just two cases turnout as benign (nodular colloid goiter with cystic degeneration) on histopathology. In present study Surgeon – performed Us FNAC has found to be 87.5% sensitive, 95.3% specific and 92.0% diagnostic accuracy. CONCLUSION: Surgeon – performed Ultrasound-guided FNAC is a safe, simple and accurate technique in the diagnosis of solitary thyroid nodule.
