目的:探讨甲状腺微小乳头癌的声像图特征与病理基础。方法:回顾性分析于2009年12月~2012年12月在我院治疗的43例甲状腺微小乳头状癌患者的声像图表现与病理特征。结果:甲状腺微小乳头癌的声像图表现为形态不规则、边界不清晰、实质不均匀的低回声结节,周围无声晕,可见微小钙化,以内部血流为主。甲状腺微小乳头癌在病理镜下观察形态多不规则,边界多不清晰,存在纤维假包膜,内部可见砂粒体,病灶内部组织由滤泡状、乳头状结构排列的纤维间质与癌细胞构成,不同病灶中三者所占的比例也不相同。结论:甲状腺微小乳头癌的病理组织学特征决定了其声像图特点。
Objective: To investigate the sonographic features and pathological basis of thyroid papillary carcinoma. Methods: Forty-three patients with thyroid papillary thyroid carcinoma treated in our hospital from December 2009 to December 2012 were analyzed retrospectively. Results: Ultrasonographic appearance of thyroid papillary carcinoma showed irregular echocardiography, unclear boundary and hypoechoic nodules with non-uniform surrounding. Small thyroid papillary carcinoma in the pathological microscopic observation of irregular shape, the border is more unclear, the presence of fibrous pseudocapsule, the internal visible sand body, the internal organization of the lesion by the follicular, papillary structure arranged in the interstitial fibrosis and cancer cells , The proportion of different lesions in the three are not the same. Conclusion: The histopathological features of thyroid papillary carcinoma determine its sonographic features.
