甲状腺髓样癌和甲状腺乳头状癌的超声特征比较

摘要

ObjectiveTo observe the ultrasonographic characte ristics of thyroid medullary carcinoma and papillary carcinoma of thyroid.Methods156 cases of thyroid cancer patients in our hospital according to the types of medullary thyroid cancer group of 34 cases and 122 cases of papillary thyroid carcinoma group. To observe the ultrasonic image of two groups of patients, analysis of patients with nodule size, location, internal structure, shape, edge, echolevel and calcification characteristics.Results In patients with medullary thyroid carcinoma of thyroid nodules is relatively large, located in upper pole, the internal structure is solid,irregular shape, irregular edge, lowecho, calciifcati on. Medullary thyroid carcinoma andpapillary carcinoma of thyroid nodules in the size, location, shape, internal structure, edge,echo level and cal cification were significantly different (P < 0.05 or 0.01).Conclusion Thenodules of medullary thyroid carcinoma has some speciifc characteristis, the ultrasound image has important reference value in the preoperative diag nosi, but for atypical nodules iseasy to be misdiagnosed, need the same calc itonin levels common diagnosis.%目的：观察甲状腺髓样癌和甲状腺乳头状癌的超声特征。方法将我院收治的156例甲状腺癌患者按类型分为甲状腺髓样癌组34例和甲状腺乳头状癌组122例。观察两组患者的超声图像，分析患者结节的大小、位置、内部结构、形态、边缘、回声水平以及有无钙化等特征。结果甲状腺髓样癌患者的结节相对较大，位于甲状腺的中上极，内部结构为实性，形态不规则，边缘不整齐，低回声，伴有钙化。甲状腺髓样癌和甲状腺乳头状癌的结节在大小、位置、形态、内部结构、边缘、回声水平及钙化等方面均差异显著（P＜0.05或0.01）。结论甲状腺髓样癌结节具有一些特异性特征，超声图像在术前诊断中具有重要的参考价值，但对于不典型的结节则容易误诊，需要同降钙素的水平共同诊断。
