Abstract:
Objective To analyze the X-ray,CT and MRI findings of giant cell tumor in the thoracic vertebrae,in order to improve its diagnostic accuracy.Methods X-ray,CT and MRI findings of 9 cases of pathologically proved giant cell tumor were analyzed retrospectively. X-ray examination was performed in 7 cases,CT in 6 cases,and MRI in 7 cases.Results Of the 9 cases with thoracic vertebrae giant cell tumors,8 involved a single vertebra while 1 case involved the left ninth posterior segment of rib simultaneously.On X-rays studies, 6 cases of bone destruction were dispensability,and 1 case was osteolysis.Three cases of vertebral destructive margin were clear. The body of vertebra was flattened in 3 cases.Pore-vertebral soft tissue masses were found in 4 cases.On CT examinations,5 cases of bone destruction were dispensability,and 1 case was osteolysis.3 cases of vertebral margin were clear with partial sclerotic rim. 4 cases of vertebral body had shade of bone-cristae.There were soft tissue masses around vertebrae in 5 cases,with vertebrae accessory,dural sac and the spinal cord involved to varying degrees.On MRI studies,hypointense were showed in 5 cases while isointense in 2 cases on T1 WI;On T2 WI,isointense was showed in 1 case,hyperintense in 4 cases,and mixed-intense in 2 cases.Conclusion Giant cell tumor in the thoracic vertebrae is uncommon.Full understanding X-ray,CT,MRI characteristics is useful to improve the diagnosis, guide clinical surgical treatment and forecast prognosis.
