[Communicating syringomyelia and syringobulbia after surgery of a spinal epidural tuberculoma].

In a 46 year old patient a syringomyelia and syringobulbia were diagnosed clinically 18 years after a transverse lesion of the cord and removal of an epidural spinal tuberculoma. Post-myelographic CT and NMR scans showed a communicating syringomyelia and syringobulbia. A flavectomy was performed and a syringopleural shunt implanted. The operation was successful by neuroradiological criteria. Clinically there was a worsening of the spastic gait during one-year follow up. Neuroradiological findings and etiology of the syrinx are discussed, and a causal relationship to the tuberculoma is proposed.
