Regarding non neoplastic lesions maximum comprised of diffuse(74%) and multi nodular goiters (16% ). Others consisted of inflammatory conditions (5%), hyperplastic nodules(4%) and simple colloid filled cysts 1%. Inflammatory conditions included Hashimotos` thyroiditis (67.3%) deQuervain`s thyroiditis (granulomatous thyroiditis) (16.3 %), Lymphocytic thyroiditis (11.7%), and Riedel`s thyroiditis(4.7%).
