School ager with worsening back pain after minor fall

Radiograph and CT of Ewing sarcoma of the spine
Lateral radiograph of the spine shows collapse of the T12 vertebral body. Sagittal 2D reconstruction and axial CT without contrast of the T12 vertebral body in bone windows shows a permeative destructive process affecting it. Axial CT without contrast of the abdomen at the T12 level shows a large left-sided paraspinal soft tissue mass.

The diagnosis was Ewing sarcoma.
