We report a case of thoracic disc herniation in a 53-year-old woman who presented to the Emergency Department (ED) with a 2-week history of acute lower back numbness and intermittent fecal incontinence. On examination, she had lower extremity hyperreflexia, an abnormal gait, and lower lumbar pain but lacked any radicular findings The purpose of this study was to determine whether the MRI signal characteristics are predictive of acuity of symptoms in patients with lumbar disc herniation (LDH).
