Clinical presentation: A 32-year-old woman was referred for evaluation of a nodular goiter discovered on screening.

Palpation: Both lobes were a bit firm, no nodules could be palpated.

Laboratory tests: TSH 2.01 mIU/L, aTPO 91 U/mL.

Ultrasound. The thyroid was composed of echonormal and moderately hypoechogenic areas. The lesion in question located in the central part of the right lobe had a similar presentation and was surrounded with halo. There was a more hypoechogenic area in the lower pole of the left lobe. Neither lesions fit to nodule.

Aspiration cytology: benign Hashimoto's thyroiditis.

Suggestion: TSH determination in every year, in the event of pregnancy at once.

Comment. The discrete lesion in the central part of the right lobe does not correspond to a nodule, it had a similar echo pattern and irregular shape.
