Clinical presentation: A 45-year-old man was referred for evaluation of a recurrent hyperthyroidism. He has been treated for hyperthyroidism for two years.

Palpation: The left lobe was enlarged and had a firm nodule.

Laboratory tests: TSH 0.001 mIU/L, FT4 43.2 pM/L, TSAb 3.9 U/L (normal value < 1.5).

Ultrasonography. The thyroid was moderately hypoechogenic and contained at least three nodules. The vascularization was increased in the extranodular part.

Cytology of the largest nodule in the left lobe resulted in benign colloid goiter.

Surgery was advised. Histopathology disclosed benign hyperplastic nodules in both lobes and chronic lymphocytic thyroiditis.
