Ewing’s sarcoma is a variety of sarcoma of reticuloendothelial origin. There are atypical forms of Ewing’s sarcoma, encountered in 20% of cases, where the tumor grows in the soft tissue without any skeletal connection. The imaging of extra-skeletal Ewing’s sarcoma (EES) has been revolutionized by the advent of modern techniques with magnetic resonance imaging (MRI) at the forefront. Magnetic resonance imaging is an essential aid for determining target volumes for radiotherapy and for monitoring patients during chemotherapy to assess its effectiveness and for the diagnosis of local recurrences. The diagnosis is mainly based on cytogenetics and immunohistochemistry. Their prognosis is a priori poor, with the possibility of local recurrence or late metastases. We report a particular case of EES located at the retrorectal space in a 15-year-old girl revealed by gluteal pain.
