Ewing's Sarcoma (ES) is a rare malignancy but 2nd most common malignant tumor of long bones after osteosarcoma usually occurring in children and young adults. Rarely, it can affect vertebra or spine in adolescent masquarading as a progressive infectious lesion. The spinal ES usually occurs in lumbar vertebrae and presents with progressive neurological deficits in lower limbs. Ewing’s Sarcoma has poor prognosis because of uncontrolled metastatic potential making early diagnosis and intervention critical for survival of the patient. We report here a case of ES in a 14-year-old girl with involvement of lumbar spine with local spread and invasion of cauda equina with radiological, histopathological and immunohistochemical features.
