Abstract:
Objective To explore the X-ray ,CT and MR manifestations of spinal giant cell tumor(GCT) for improving the diag-nosis level of this rare disease .Methods The X-ray ,CT and MR data in 16 cases of spinal GCT were retrospectively analyzed on the location ,size ,morphology ,margin ,CT density/MR signal intensity and enhancement pattern .Results 4 cases located in cervical vertebra ,8 cases in thoracic vertebra and 4 cases in lumbar vertebra ;in which ,6 cases only involved in vertebral body and other 10 cases involved in vertebral body and and appendix .The lesion affected two neighboring vertebrae in 8 cases ,and affected only one vertebra in the remaining 8 cases .16 cases were protruded into the spinal canals and oppressed the spinal cord .The prominent X-ray and CT images showed eccentric growth ,osteolytic and swelling bone destruction .MR showed isointensity or slight hypointensity on T1WI ,and isointensity or slight hyperintensity on T2WI .After intensified scanning ,the solid portion showed marked inhomoge-neous enhancement .Conclusion Spinal GCT has certain imaging characteristics .CT and MR examination could accurately display the extent of lesion and tumor involvement ,which provides more accurate image information for formulating the strategy of clinical therapy .
