Imaging and pathology of the thyroid functional nodule. A Thyroid ultrasonography. The arrow reveals an inhomogeneous weak echogenic nodule in the left lobe of gland, about 21*16*29 mm in size, ill-defined margins, irregular shape. B Radionuclide imaging. A hot nodule in the left lobe of the gland corresponding to the weak echogenic nodule detected on ultrasound. C and D Fine needle aspiration cytology of the functional nodule (C*200-fold, D*600-fold). (D1) The arrow indicates nuclear grooves. (D2) The arrow indicates intranuclear pseudoinclusions. E and F Hematoxylin and eosin staining of the functional nodule (E*tenfold, F*100-fold). E The arrow indicates the ill-defined margins and irregular shape
