Clinical, sonographical and cytological comparison of toxic and non-toxic thyroid nodules

Aim: To compare patients with toxic and non-toxic nodular/multinodular goiter in terms of clinical, sonographical and cytological features. Material and Method: The medical data of 326 patients were reviewed retrospectively. Clinical and sonographic features were examined. Four hundred and eighty-one nodules were compared sonographically and cytologically. One hundred twenty-four patients had toxic nodular goiter and 202 of them had non-toxic nodular goiter. Results: The toxic nodular goiter group was older, they had more male sex, more multi-nodularity, larger thyroid glands and nodules with more sonographically suspicious features (p 40 mm in 13.9% of the nodules in the toxic group and 5.4% of those in the non-toxic group (p= 0.003).
