弥漫硬化型甲状腺乳头状癌的声像图表现

Ultrasound features of diffuse sclerosing variant of papillary carcinoma of the thyroid

目的分析弥漫硬化型甲状腺乳头状癌（DSV）的声像图表现。方法分析20例DSV患者的术前声像图表现和临床特点。结果20例DSV患者，累及甲状腺单侧叶12例，双侧叶8例，伴颈部淋巴结转移18例（90％）。声像图为一侧叶或双侧叶甲状腺内的弥漫性病变，所有病例均有沙粒状钙化，弥漫性散在分布于受累的甲状腺内；病变叶血流信号1级75％，2级25％。结论DSV声像图具有特征性的表现，即甲状腺弥漫性改变、沙粒状钙化和颈部淋巴结转移，超声可以作出正确诊断。

Objective To evaluate the ultrasound （US） features of diffuse sclerosing variant （DSV） of papillary carcinoma of the thyroid. Methods The US and histopathlogical of 20 DSV patients were retrospectively assessed. Results Among the 20 cases,thyroid single lobe of 12 cases, bilateral lobes of 8 cases and cervical lymph nodes metastases of 18 cases （90%） were involved in DSV of papillary carcinoma of the thyroid. At ultrasound, echo diffuse abnormal change of single lobe or bilateral lobes of thyroid and diffuse scattered microcalcifications were seen in the DSV of papillary carcinoma of the thyroid. The blood flow signals of the abnormal lobes were occupied by 75 % of one grade and 25% of two grades. Conclusions DSV of papillary carcinoma of the thyroid is usually manifested as echo diffuse abnormal change, diffuse scattered microcalcifications and cervical lymphocytic infiltration on ultrasound in relatively young patients.
