title: Delayed Spinal Epidural Hematoma after En Block Spondylectomy for Vertebral Ewing's Sarcoma.
abstract: We report here on a case of a 23-year-old male who received en block spondylectomy for a vertebral Ewing's sarcoma at our hospital. Nine days after surgery, he presented with severe back pain and motor weakness of the lower extremities. Based on the physical examination and the computed tomography scan, he was diagnosed with acute cauda equina syndrome that was caused by compression from an epidural hematoma. His neurological functions recovered after emergency evacuation of the hematoma. This case showed that extensive surgery for a malignant vertebral tumor has a potential risk of delayed epidural hematoma and acute cauda equina syndrome and this should be treated with emergency evacuation.
