X-ray (a) lateral (b) oblique reveals a permeative pattern of destruction with ill defined margins in proximal femoral shaft with resorption of overlying cortex.: Ewing's sarcoma. (arrowhead) depicts interrupted, & (arrow) showing multilaminated periosteal reaction. MRI (c) T2W coronal (d) T2W FAT SAT sagittal, (e) Post contrast coronal T1W Images reveal heterogeneous enhancing mass lesion in proximal tibia with extension into overlying soft tissue involving cortex. (f) Nuclear scan revealing intense uptake within the lesion (arrow). (c) Microscopic histopathology smear showing sheets of round cells.
