Abstract

Multinodular goiter (MNG) is one of the benign thyroid neoplasm and nodular hyperplasia is the most common pathologic type. MNG could be misdiagnosed as a malignancy because of its characteristic, which is its growing tendency. A-70-year-old female was referred to our clinic from endocrinology, with the huge and recently rapid growing thyroid mass. We performed the neck sonography, its guided fine needle aspiration cytology (FNAC), neck CT and MRI. She was presumed as the malignant thyroid neoplasm except papillary carcinoma. The right completion thyroidectomy and anterior compartment neck dissection had been done and the nodular hyperplasia was diagnosed finally. We learned a valuable lesson from this case in the following. Even if the malignancy is strongly suggested in the radiology and clinically, more careful consideration in determining the surgical method and its extent is mandatory.
