[Imaging diagnosis of thyroid carcinoma with bone metastasis]
1Department of Radiology, Affiliated Hospital of Guilin Medical College, Guilin 541001, China.
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.

Description of the Procedures
Computed Tomography (CT) scan:
Computed Tomography (CT) scans use X-ray technology to generate detailed images of bones, organs, and tissues. During the scan, the patient lies on a moving table...

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
