Clinical presentation: A 49-year-old man was referred for an evaluation of a nodular goiter detected on screening.

Palpation: The left lobe was enlarged and multiple nodules were palpable.

Functional state: euthyroidism with TSH-level 0.65 mIU/L.

Ultrasonography: The right thyroid contained a moderately hypoechogenic, the left had multiple nodules.

Cytology was performed from the nodule in the right lobe, from the calcified part and from the moderately hypoechogenic nodule in the left lobe. The cytological patterns were identical in all three cases and yielded benign, colloid goiter.

The patient was operated because of the size of the left lobe.

Histopathology: disclosed benign, hyperplastic nodules.

Comment.

It is worth analyzing the nodule in the right lobe. At first sight it has spiculated margins, however thorough analysis reveals that the irregularity of the margin is caused by the impression of another nodule next to. There is a nodule having macrocalcification. The dorsal part of this lesion seems to be blurred, but this is caused only by the acoustic shadow.
