Damage to the spinal cord/conus medullaris due to incorrect identification of the lumbar space is a known complication of lumbar puncture. However, damage to a low-lying cord using an appropriate interspace is extremely rare. We describe a 26-year-old woman who underwent emergency caesarean section under spinal anesthesia. She developed right foot drop immediately after surgery, which gradually recovered over the next 10 months. Magnetic resonance imaging revealed a low lying cord with a fatty filum terminale and intramedullary T2 hyperintensity, suggestive of needle damage.
