What are the findings?
Sclerotic appearance of L5 vertebra. Suggestive of Ewing sarcoma though the location is atypical.
What is the differential?
Osteoma, Ewing sarcoma, fibrous dysplasia, metastasis, lymphoma, enchondroma
The L5 vertebra shows diffuse homogeneous increased attenuation relative to the rest of the spine. Prevertebral soft tissue mass. The appearances are consistent with sclerosis, in this case due to Ewing sarcoma.
