We report on a woman who presented with a history of lower limb weakness and numbness for a few months. Based on cross-sectional imaging, at first she was provisionally diagnosed to have an aggressive tumour around the spinal column. Pathologically, the lesion was proved to be a primitive neuroectodermal tumour / Ewing's sarcoma. Herein, we discuss the clinical, radiological, and pathological features of this disease entity.
