摘　　要：目的通过探讨甲状腺癌骨转移影像学特点,提高甲状腺癌诊断水平。方法回顾性分析2011-2012年20例甲状腺癌患者的影像学资料。结果 20例患者均为甲状腺癌骨转移,先发现骨转移病灶,后查出甲状腺癌的14例;先发现甲状腺癌原发病灶,后查出骨转移6例。12例患者骨转移多发于上半身的骨骼,8例呈现溶骨型,表现为大片状、地图样骨缺损及囊状破坏区;4例为成骨型,表现为片状、棉絮样致密影。结论甲状腺癌极易发生骨转移,主要是以溶骨型为主,另有成骨性转移。X线及CT检查均有特征性改变,能够为甲状腺癌诊断提供可靠的影像学依据。Objective To improve the diagnostic level of thyroid carcinoma through discussion on imaging features of bone metastases from thyroid carcinoma.Method Imaging data of 20cases of patients with thyroid carcinoma from 2011to 2012was analyzed retrospectively.Results 20cases of patients all had bone metastases from thyroid carcinoma.There were 14cases in which bone metastases were found earlier and thyroid carcinoma was diagnosed later;there were 6cases in which primary tumor of the thyroid carcinoma was found earlier and bone metastases were diagnosed later.Bone metastases in 12case of patients were mainly in bones of the upper body segment.8cases was of osteolytic type,which was shown as large flake and map like bone defects and cryptomere destruction zone;4cases of osteoblastic type,which was shown as flake and cotton wool like dense shadow.Conclusion Thyroid carcinoma can easily present with bone metastases which are mainly of osteolytic type,and there are also osteoblastic metastases.X ray and CT examination have characteristic improvement and can provide reliable image basis for diagnosis of thyroid carcinoma.
