摘　　要：目的探讨甲状腺钙化模式在诊断甲状腺癌中的意义。方法对121例共191个甲状腺结节行术前超声检查。结果72个(38%)结节内发现钙化,其中41个(57%)结节被组织病理证实为甲状腺癌,按照钙化分型,伴微钙化的结节12个(86%),伴粗钙化的结节23个(52%),伴周边钙化的结节5个(45%),周围无甲状腺结节的孤立钙化斑1个(33%)被证实为甲状腺癌。结论钙化是诊断甲状腺癌的一个特异性的指标,从筛查甲状腺癌的角度来讲,声像图中的每一种钙化都有恶性的风险,不仅微钙化,其他类型的钙化也要仔细检查。Objective To evaluate significance of thyroid calcification sonographic patterns in the diagnosis of thyroid carcinoma. Methods 191 thyroid nodules in 121 patients were examined on preoperative ultrasonography. Results Calcification was detected in 72（38%） nodules, 41（57%） of which was histologically diagnosed as carcinoma. According to the calcification types, 12（86%） nodules with microcalcification, 23（52%） nodules with intranodular coarse calcification, 5（45%） nodules with peripheral calcification and 1（33%） solitary calcified spots without surrounding tumor were diagnosed as cancer. Conclusion Calcification is a characteristic index for thyroid carcinoma, from the perspective of carcinoma screening, any type of sonographically detected calcifications represents a risk of malignancy, not only microcalcification, but other types of calcification should also be thoroughly examined.
