Syringomyelia following Listeria meningoencephalitis: report of a case.

A case of symptomatic syringomyelia which appeared six years after Listeria meningoencephalitis is described. Chronic spinal arachnoiditis, as shown by standard MRI and dynamic phase contrast (PC) cine-MRI, may occur after spinal infection and is likely the cause of syringomyelia. To our knowledge, there are no previous reports of delayed spinal complications following Listeria monocytogenes infection. The possibility of developing syringomyelia should be always considered in any patient with a history of central nervous system infection.
