Cauda equina syndrome presenting as a herniated lumbar disk.

Cauda Equina Compression (CEC) is a clinical syndrome consisting of low back pain, bilateral sciatica, saddle anesthesia, bilateral lower extremity weakness, and even frank paraplegia with bowel and bladder incontinence. At the onset of CEC, the clinical picture may resemble typical intervertebral disk disease with low back pain and unilateral sciatica. The back pain is severe, overshadowing the leg pain, and should alert the physician to the periodic evaluation of the patient and evidence of a progressive neurologic deficit. Early discovery of CEC is necessary if neurologic recovery is to be expected from decompressive laminectomy.
