It also showed a focally disrupted aggressive periosteal reaction throughout the distal half of the clavicle, with a swollen overlying soft tissue ( Figure 1 ).
MRI of the shoulder revealing a 10.1 x 4.1 x 3.3-cm expansible intramedullary lesion on the left clavicle bone with intermediate T1 heterogeneous signal and low hyper T2 with heterogeneous enhancement, which likely corresponded to Ewing sarcoma.

The magnetic resonance imaging result showed a 10.1 x 4.1 x 3.3-cm, expansible, intramedullary lesion at the left clavicle bone with intermediate T1 heterogeneous signal and hyperintensity T2 with heterogeneous enhancement, which suggested Ewing sarcoma ( Figure 2 ).
Radiograph of the left clavicle at 1 month after surgery and reconstruction. The patient showed no signs of recurrence or disease progression.
