Emergency Medical Minute

Release Date: 05/09/2019

Author: Erik Verzemnieks, MD

Educational Pearls:

  • Cauda equina syndrome is caused by the compression of the nerve roots that extend beyond the termination of the spinal cord
  • Trauma, infection, hematoma, disc rupture/herniation can cause this - basically anything that can cause pressure and fill space
  • Symptoms can include saddle anesthesia, lower extremity pain, numbness, incontinence, and constipation
  • Post-void residual that is abnormally high may be an indicator
  • MRI is diagnostic modality of choice
  • Emergent surgical decompression is treatment
