Abstract
We report one case of spinal epidural hematoma. She is a 66-years-old female. She felt severe back pain without an inducing factor. The next day, she became unable to walk and use her left upper extremity. She also showed urinary incontinentia. Her muscle weakness improved a little bit by bed rest. But the 4th day after onset, her paralysis increased, and the decompression surgery was performed. Post operative course is good and now she is able to work as a keeper of her shop. We describe the great value of MRI diagnosing this lesion. The factors indicating the post operative course in this lesion were discussed. The severity of pre-operative palsy showed a high relationship to the prognosis.
