title: Intramedullary and extramedullary schwannoma of the cervical spinal cord--case report.
abstract: Intramedullary schwannomas and neurofibromas are rare tumors. Only two cases have been reported as having both an intramedullary and extramedullary component. We have managed the case of a 15-year-old girl with a schwannoma that appeared to track along the sensory nerve root into the spinal cord. The clinical presentation in this case was that of motor weakness and atrophy, sensory abnormalities, and, late in the course, pain. Magnetic resonance imaging with gadolinium enhancement was better than myelography and computed tomography at delineating the intramedullary extent of the tumor. The tumor was removed microsurgically at two operative sittings. Reports of this unusual pathology are reviewed.
