Reason: 61-year-old female with lower extremity weakness and numbness with upgoing babinski for several months, history of ALL. There continues to be no nodular enhancement involving the conus or cauda equina nerve roots. An isolated right-sided linear enhancing structure represents a congenital radicular vein. There remains minimal enhancement of cauda equina nerve roots which again are enhancing less so compared to the previous exam. These findings are nonspecific but may represent an inflammatory process. The conus medullaris shows normal signal. Alignment is notable for unchanged minimal retrolisthesis of L1 relative to L2 which is associated with desiccation and mild disc height loss. The other intervertebral discs are preserved in height. The vertebral bodies are preserved in height. There is no significant neuroforaminal or spinal canal stenosis. The bone marrow signal is preserved. There are changes of presumed bone marrow biopsies in the posterior iliac bones. These findings are unchanged.
