UNASSIGNED: To study high-frequency ultrasound features and pathological characteristics of @entity259 ( @entity259 , @entity11166 ) with the purpose to improve the diagnostic accuracy of this disease. The clinical data of 20 cases of @entity1 with @entity11166 confirmed by the clinical surgery were retrospectively analyzed. And the high-frequency ultrasound features were analyzed and compared with the pathological characteristics. There were 16 cases with @entity5 invasion into one side of the thyroid gland; 17 cases with @entity5 in the middle-upper pole of the thyroid gland. And 8 cases were detected with uneven echo of high frequency ultrasound appearance and pathological manifestations of @entity528 to @entity39 seen under the light microscope or normal thyroid tissue within part of the lump. 16 cases were tested with even echo of high frequency ultrasound appearance, and @entity5 cells were formed in the solid and block-like shape under the light microscope. And 18 cases were manifested with low echo, with proliferation of fibrous tissue within the intercellular substance under the light microscope. 18 cases could be seen the @entity730 points and often amyloid-like content deposited in the intercellular substance seen under the light microscope. In addition, the pathological manifestations of the 8 cases combined with lymph node @entity3 were the "lash @entity5 " of the metastatic lymph nodes and @entity5 . @entity11166 was commonly located in the middle-upper region of the thyroid gland and in one leaf of the thyroid gland, combined with lymph node @entity3 . The high frequency ultrasound appearance was the even low-echo @entity5 in round or quasi-circular shape, with obscure boundary and often combined with rough @entity730 . High frequency ultrasound could be used as the prior physical diagnostic method for @entity259 .
