title: Spinal Ewing sarcoma: misleading appearances.
abstract: The plain radiographic and computed tomographic (CT) findings in two unusual cases of spinal Ewing sarcoma are reported. Radiographic features resembling neuroblastoma in one case and aneurysmal bone cyst in the other were present. These findings may be misleading and distinguishing characteristics in each case are discussed.
