AbstractEwing's sarcoma is one of the most common malignant tumors of the musculoskeletal system in children, adolescents and young adults. Early recognition of this sarcoma and early treatment improves outcome. In the event of pelvic involvement, patients may have spinal symptoms and radiographic findings similar to discogenic pain or sacroiliitis. In this report. a 21-year-old male, who had clinical features mimicking unilateral sacroiliitis and lumbar disc syndrome, is described. His advanced radiographic evaluation and biopsy demonstrated Ewing's sarcoma of the pelvic girdle. Pelvic tumors in the differential diagnosis of low back pain are discussed.
