Findings: Right and left lobes of the thyroid gland are slightly enlarged measuring 5.1 cm in greatest dimension each. Within the lower pole of the right lobe thyroid gland is a slightly hypoechoic fairly well circumscribed 6mm mass, which demonstrates some internal vascularity. No microcalcifications are seen. Within lower pole of the left lobe thyroid gland is a slightly hypoechoic, slightly vascular 2.1 cm mass. No microcalcifications are seen.
Is FNB the only option? I want to know if there is an alternative which is less invasive?
