Hydrosyringomyelia of the conus medullaris associated with a thoracic meningioma

Abstract

✓ The case of a 73-year-old woman found to have hydrosyringomyelia associated with a lower thoracic meningioma is reported. Possible mechanisms for the formation of the hydrosyrinx are discussed, with particular attention being paid to the possibility of transmural passage of cerebrospinal fluid into the central canal.
