title: The conus demyelination syndrome in multiple sclerosis.
abstract: Bowel, bladder and sexual dysfunction are common in multiple sclerosis and are generally attributed to the widespread nature of the involvement of the neuroaxis by the demyelinating plaques. Recently we encountered a specific subset of patients within this group who had characteristic clinical complaints of hesitancy, straining and incomplete voiding, perineal hypesthesia on examination, areflexia by cystometry and colonometry and electrophysiological parameters suggesting involvement of the conus medullaris. This heretofore postulated but undocumented mechanism of neurovisceral dysfunction in multiple sclerosis is detailed and discussed in 2 patients in this report.
