[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.


CONCLUSIONS
Bone metastasis is common in thyroid carcinoma, manifested typically by bone lysis with occasional osteogenic metastasis.
