The Imaging Analysis of Giant Cell Tumor of Bone in Atypical Locations

Objective: To analyze imaging of giant cell tumor of bone in atypical Locations on plain film,CT and MRI.Methods: Nineteen cases with histologically confirmed giant cell tumor of bone in atypical Locations were reviewed.Radiography was performed in 19 cases,CT in 19 cases and MRI in 16 cases.Results: giant cell tumor of bone located at sacral in 9 cases,at ischial in 4 cases,at metatarsal in 2 cases,metacarpal,wrist,shoulder blades,lumbar each one case.Expanding growth and osteolytic destruction were on X–ray or CT,without hardened edge.MRI show low to intermediate signal on T1WI,hyperintensity on T2WI.Conclusion: Use of various imaging methods can improve the understanding of giant cell tumor of bone in atypical Locations,to make an accurate diagnosis.
