Evaluation of Thyroid Lesions Using Fine Needle Aspiration Cytology
Background: Discrete thyroid swelling is common clinical presentation with prevalence rate of
4-7% in the general population. Now fine needle aspirate cytology (FNAC) is very important
technique for diagnosis of thyroid nodules, as it is very simple, safe, less invasive technique.
Objective: To evaluate the diagnostic accuracy of FNAC in Thyroid Nodules.
Patients and Methods: Study carried out on patients who visited the Outpatient Clinic of
General Surgery Department, Qena University Hospital complaining of thyroid nodules, in the
period from April 2017 to July 2018
Results: Out of the 100 patients 76 were females and 24 males. The age ranged from 11-60
FNAC showed overall diagnostic accuracy of 97.01% with specificity of 98.39 %, sensitivity of
80.00% for malignant lesions, positive predictive value of 80.00% for malignancy and negative
predictive value of 98.39%.
Conclusion: FNAC is an invaluable and minimally invasive procedure for pre-operative
assessment of patients with a thyroid nodule. FNAC has high sensitivity in picking up
