 There are numerous foraminal and extraforaminal lumbar and sacral nerve root tumor that appear to not have significantly changed in size since 2014. Likewise, there are several tumors in the paraspinal soft tissues, which appear to be similar in size as before. There is degenerative spondylosis in the lower lumbar spine. In particular, a disc protrusion at L5-S1 has decreased in size considerably since 2014 and there is now minimal spinal canal narrowing as a result. However, there has been increased loss of disc space height at L5-S1 and increased degenerative bone marrow signal alterations at this level. There is no significant spinal canal stenosis at the other lumbar spine levels. There is no spondylolisthesis and the vertebral body heights are essentially preserved.
1. The numerous lumbosacral nerve root and paraspinal soft tissue neurofibromas do not appear to have changed significantly since 2014.2. Interval evolution of the degenerative disc disease, with involution of the disc protrusion at L5-S1, with minimal residual spinal canal narrowing, but increased loss of disc space height at L5-S1.
