A probable extraordinary etiology of a reduntant nerve root syndrome : lomber spondylolisthesis

The description of redundant nerve root syndrome (RNRS) is known as large, elongated and tortuous nerve roots with a severe lumbar stenosis. It is considered that the cause is chronic compression of the nerve roots. To the best of our knowledge, this is the first case of RNRS related with lumbar spondylolisthesis without lumbar canal stenosis in the English literature. In this case report, we have presented a patient who had been diagnosed as RNRS in association with lumbar spondylolisthesis. The Magnetic resonance imaging (MRI) and peroperative observation of the clinical entity are discussed.
