【摘要】 目的结合疾病病理特点,探讨甲状腺未分化癌和甲状腺乳头状癌超声成像特征的差异。方法选取2010年1月至2015年6月在本院接受治疗并经病理证实为甲状腺未分化癌的患者12例为观察组,另选取同期经病理证实为甲状腺乳头状癌的患者35例为对照组,观察两组患者临床特征和超声特征。结果女性患者所占比例大,观察组患者病灶平均直径大于对照组,纵横比<1的比例高于对照组,且观察组病灶微钙化程度高、血流少不规则、超声回声更不均匀、边界更为模糊,以上差异均有统计学意义(P<0.05)。两组患者超声特征中病灶形态、囊性变、回声、被膜受侵的对比差异无统计学意义。结论甲状腺癌患者以女性为主,未分化癌患者病灶纵横比一般都<1且具有微钙化程度高、血流少不规则、超声回声更不均匀、边界更为模糊的特点,值得临床参考。更多还原

【Abstract】 Objective To discuss the differences of ultrasound features between anaplastic thyroid carcinoma and papillary thyroid carcinoma. Methods Patients were selected from January 2010 to June 2015 in our hospital for treatment and twelve patients with pathologically confirmed anaplastic thyroid cancer as the observation group,another 35 cases over the same period with pathologically confirmed papillary thyroid carcinoma were selected as the control group. Clinical features and ultrasound characteristics of the two groups were analyzed. Results Women accounted for a large proportion of patients with thyroid cancer. Mean diameter of the disease was greater in anaplastic thyroid cancer patients,who were more likely to be lesions ratio <1,had higher micro calcification,less blood irregularity,more ultrasound echo uniformity,and more blurred boundaries;all the above differences were statistically significant(P<0.05). Characteristics of the two groups of patients with lesions in ultrasound morphology,variants,echo,and contrast cystic capsule invasion were not statistically significant. Conclusions Thyroid cancer is female-dominated. Anaplastic thyroid cancer patients are generally with undifferentiated aspect ratios <1 and have a higher degree of microcalcifications,less irregular blood flow,more ultrasound echo uniformity,more fuzzy boundary characteristics,which is worthy of reference.更多还原
