Abstract:
Purpose:Analysing the imaging performance of solitary plasmacytoma of spine,to raise the awareness and the diagnosis accuracy.Materials and Methods: Five cases of spinal solitary plasmacytoma confirmed by clinical pathology were retrospectively analysed,to sum up the imaging performance characteristics.Results: All lesions were single vertebra involved,3 cases in thoracic and 2 cases in lumbar,3 cases occurred vertebral compression fracture.X-ray and CT showed osteolytic destruction,expansive growth and soft tissue mass,MRI showed diversity of signals,and remarkable enhancement after contrast injection.Conclusions: X-ray presents lower diagnostic sensitivity,but contributes to exclude multiple myeloma.CT and MRI can depict the morphological features and extent of tumor regions definitely,CT shows better than MRI on the thickening trabecula and residual bone in the tumor,MRI can provide a lot of information for plasmacytoma,including the diagnosis,identification and staging,which is considered as the best imaging diagnostic methods of plasmacytoma.
