Clinical presentation: On evaluation of pericardial fluid, thyroid nodule was diagnosed in a 51-year-old woman.

Palpation: a firm nodule in the right lobe.

Laboratory tests: TSH 1.60 mIU/L.

Ultrasonography. The thyroid was echonormal. Two nodules were found in the right lobe. The upper-lateral one was hypoechoic and showed back wall cystic figures. There was a dominantly hypoechoic other nodule in the middle, ventro-lateral part of the lobe. The lesion had numerous microcalcifications, irregular, lobulated margins and showed taller-than-wide shape.

Cytology resulted in papillary cancer.
