Sonographic appearance of ewings sarcoma of femur: a case report

Abstract

Ewings sarcoma is the second most common bone tumor after osteosarcoma in children and adolescents. Diagnosis of skeletal Ewings sarcoma is usually based on MRI and histopathological findings. But one should be aware of the ultrasonographic appearance of this tumor as this may aid in the initial diagnosis. We report a case of Ewings sarcoma of the femur in which a periosteal reaction, cortical destruction, and Power Doppler on sonography suggested a probable malignant diagnosis.
