| [摘要] 目的：探讨甲状腺髓样癌（MTC）超声特征。方法：回顾性分析40个MTC超声表现，以60个甲状腺乳头状癌（PTC）及97个甲状腺良性结节为对照，分别比较MTC与PTC及甲状腺良性结节在病灶数量、直径、边界、形态、纵横比、囊性成分、实性部分回声、钙化、血供及颈部淋巴结等方面的差异性，归纳其声像图特征。结果：MTC体积较大，低回声（97.5%），实性（92.5%），A/T＜1（97.5%），边界清晰（62.5%），形态规则（45%），可有钙化（32.5%为粗钙化、25%为微钙化），血供丰富（95%），淋巴结转移（65％）。7例MTC术前检测血清降钙素均显著升高。结论：MTC具有甲状腺恶性肿瘤的一般超声特征，但又与常见的PTC不同，具有其自身特点，不典型MTC易误诊为甲状腺良性结节，可结合血清降钙素检测及细胞学穿刺活检综合判断。 |

| Abstract: |
| [Abstract] Objective: To investigate the ultrasonographic characteristics of medullary thyroid carcinoma (MTC). Methods: A retrospective analysis sonographic features of 40 MTC. For comparison, ultrasound appearances of 60 thyroid papillary carcinoma and 97 benign thyroid nodules were evaluated also.The differences in the lesion number, diameter, boundary, shape, aspect ratio, cystic component, solid partial echo, calcification, blood supply and neck lymph node of MTC and PTC and thyroid benign nodules were compared respectively, and the features of MTC were summarized. Results: The MTC was large, hypoechoic(97.5%), solid（92.5%）,A/T < 1 (97.5%), clear boundary (62.5%), morphological rules (45%), can have calcification (32.5% coarse calcification, 25% microcalcification), blood supply is rich (95%),lymph node metastasis（65％）. Serum calcitonin levels were significantly increased in 7 MTC preoperation. Conclusion: MTC has general ultrasonic characteristics of thyroid malignant tumor, but it is different from common PTC and has its own characteristics. Atypical MTC is easily misdiagnosed as benign thyroid nodule. It can be combined with serum calcitonin detection and cytological biopsy. |
