Toxic Multinodular Goiter in a Patient Who Has Been Followed Up with the Diagnosis of Hashimoto Thyroiditis and Has Normal TSH Values
Nodular thyroid disease arises from the increased proliferation rate of thyroid cells. Thyroid scintigraphy is considered as the gold standard imaging method for the diagnosis of thyroid nodules with autonomous function. Autonomously functioning thyroid nodules (AFTN) are defined as palpable nodules that are larger than 1 cm on ultrasonography demonstrating a focally increased uptake on thyroid scintigraphy. Practicing technetium scintigraphy for thyroid nodules is only recommended in the presence of suppressed or subnormal plasma TSH levels. However, this may result in underdiagnosis of these nodules in iodine-deficient countries. We hereby present a case with AFTN despite the presence of normal TSH values.
