Acquired elongation of nerve roots due to the mechanical trapping at the level of lumbar spinal stenosis is assumed to be the possible mechanism. It is believed that the cause is a squeezing force due to the chronic compression. The most common clinical symptoms are low back pain and leg pain. Although lumbar spinal canal stenosis is common, the entity has rarely been discussed in the literature. Here we present the MR imaging and intraoperative appearance of the condition with a brief discussion in a 71-year-old woman.
