甲状腺癌骨转移的影像学诊断

目的分析甲状腺癌骨转移的临床及影像学表现，探讨其临床及影像特点和诊断价值。方法经病理证实为甲状腺癌骨转移10例，对其X线、CT表现进行回顾性分析。10例均行X线平片检查，其中3例做CT扫描。结果甲状腺癌具隐匿病史，在骨转移病例，先发现骨转移，后查出原发灶者3例，7例在原发灶或甲状腺结节的基础上出现骨转移。甲状腺癌骨转移以溶骨性转移为主，多发于上半身的骨骼，表现为膨胀性囊状破坏区，呈大片状、地图样骨缺损，范围大、广泛为其特点。结论甲状腺癌可发生骨转移，以溶骨型为主，可有成骨性转移。

Imaging diagnosis of thyroid carcinoma with bone metastasis]

OBJECTIVE: To study the clinical and imaging features of thyroid carcinoma with bone metastasis and evaluate the importance of the imaging diagnosis in such cases. METHODS: A retrospective analysis was performed on the results of X-ray and CT examinations of 10 pathologically confirmed patients (including 2 men and 8 women aged from 40 to 89 years with a mean age of 61 years) with thyroid carcinoma with bone metastasis. RESULTS: Thyroid carcinoma was latent in terms of its disease history. In these cases, the primary tumors were identified after the bone metastasis in 3 cases, and the bone metastasis occurred on the basis of the primary lesions or the thyroid gland nodules in 7 cases. Thyroid carcinoma with bone metastasis occurred mostly in the skeleton of the upper body, characterized mainly by cystic expansion of the bone tissue destruction causing extensive patchy map-like bone defects. CONCLUSION: Bone metastasis is common in thyroid carcinoma, manifested typically by bone lysis with occasional osteogenic metastasis.
