HUGE ADENOMATOUS GOITER REACHING THE AORTIC-ARCH WITH ELEVATED THYROGLOBULIN

We report a 14 year-old girl with a huge adenomatous goiter in the lef t lobe of the thyroid gland reaching the aortic arch with elevated thy roglobulin, The tumor grew rapidly for two years since the initial dia gnosis as an euthyroid hemilateral goiter, Ultrasonography revealed mu ltinodular tumors and magnetic resonance imaging made clear the lower expanding site of the tumor. We recommend careful follow up of hemilat eral diffuse goiters by ultrasonography for earlier detection of nodul ar changes as seen in our case.
