Multiple spinal intradural schwannomas in the absence of von Recklinghausen's disease.

A case of multiple spinal schwannomas is reported without any evidence of other manifestations of neurofibromatosis. Although cases of multiple schwannomas have been described in the setting of "Schwannomatosis," this case is unique in that all tumors were within the spinal canal. The presence of a schwannoma should prompt a complete investigation for other tumors of the nervous system preferably with magnetic resonance imaging.
