甲状腺癌的影像学诊断与病理对照

Imaging diagnosis of thyroid carcinoma with pathololgic correlation

目的:提高甲状腺癌的认识及术前诊断的准确性。方法:复习50例经手术及病理证实的甲状腺癌的影像学资料,总结影像学特征。结果:甲状腺癌病例中女性多于男性,发病部位以右侧多见,病理上以乳头状癌最常见。甲状腺癌癌瘤形态不规则,边界不光整,界线不清,密度不均匀,彩超表现为肿瘤内部血流信号丰富,后方回声衰减。CT示甲状腺病灶实性区不均匀的低密度,边缘不光整。增强CT后肿瘤呈不均匀强化,病灶境界模糊。结论:甲状腺癌具有某些共同的影像学特征,对术前诊断及鉴别诊断、确定手术范围具有一定意义。

Objective： To investigate the medical imaging features of thyroid carcinoma to promote diagnostic accuracy. Methods： A retrospective review was performed on 50 cases of thyroid carcinoma confirmed by surgery and pathology. The medical imaging charcters were summed up.Results：Women are affected on pathology, papilloma is most of common. The conformations of the tumors were irregular, with unsmooth margin. The density of the tumors was not equal. The uhrasonographic manifestation, containing microcalcifieation and abundant color signals. After contrast administration, solid part enhanced while cystic part did not enhance, but the fringe is blurred. Conelusion：Thyroid carcinoma has some collective medical imaging characters. It is significant in differential diagnosis before operation.
