Ewing Sarcoma of Soft Parts: About Three Cases and Literature Review

Abstract

Extraosseous Ewing sarcomas (EESs) are rare tumours originating from soft tissues. Imaging has an interest in the diagnosis of lesions, local extension and post-treatment follow-up. This paper reports tree cases of soft tissue Ewing's sarcoma. They all benefited from an MRI with the T1 and T2 weighted sequences in all three planes and FATSAT without and after gadolinium injection in all three planes. The guided echo biopsy was done for all the cases objectifying Ewing's sarcoma. They were treated by a multidisciplinary approach including surgery, chemotherapy and radiotherapy.
