Discussion

UBC is the lytic lesion with no or little expansion.GCT is the expansile lytic lesion after skeletal maturity, involved epiphysis at the articular surface.CMF may be indistinguishable. but solid in MRI with no fluid-fluid levels. Metastases are usually multi focal & destructive. Telangiectatic Osteosarcoma shows soft tissue extension. ABC is the best diagnosis in this young patient. It is expansile lytic lesion involved long bones.It shows fluid levels in MRI.

 

Final Diagnosis

Primary ABC
