Congenital anatomical anomalies of the lumbosacral nerve root are a rare condition.
Various types of anomalies of the lumbosacral nerve roots have been described in the
literature. Undiagnosed lumbosacral nerve root anomalies are at risk for iatrogenic
injury, may contribute to wrong-site surgery, and contribute to continued postoperative
symptoms. Here, we present the case of a 45-year-old female with discogenic back pain
and L5 radiculopathy who found to have a duplicated left L5 nerve root intraoperatively.
