Spinal Giant Cell Tumor:Imaging Features and Its Clinical Value / 实用放射学杂志

ABSTRACT

Objective To study X-ray, CT and MRI features of the spinal giant cell tumors (GCT)and to assess the clinical applied value.Methods Thirty cases of GCT of spine (13 males and 17 females with ages ranging from 17 to 69 years) were reviewed. Allcases underwent radiography,CT was done in 22 patients and MRI was performed in 16 cases.Results One lesion localized in cervical spine,10 in thoracic, 6 in lumbar and another 13 lesions in the sacrum.Osteolytic destruction and vertebral compression were seen on X-ray film. The main CT signs were expanding bone destruction and soft tissue mass. MRI showed low to intermediate signal intensity on T_1WI while high signal on T_2WI.Conclusion X-ray, CT and MRI are of significant value in diagnosis of the spinal GCT, and play an important role in surgical planning.
