Spinal cord tumor in a patient with multiple sclerosis: case report.

The association between multiple (MS) sclerosis and cerebral gliomas has been sporadically reported in the literature, causing a long lasting discussion if these lesions occur coincidentally or if MS plaques may actually lead to the genesis of gliomas. We report a 36 year old man who developed a rapid onset of right side weakness and loss of vision, having established a diagnosis of MS which was confirmed by CSF analysis and MRI. Nine years later he developed progressive tetraparesis, leading initially to suspicion of illness relapse and a demyelinating plaque in the spinal cord. However, after MRI investigation, a spinal cord tumor was diagnosed. The patient underwent cervical spine laminotomy for microsurgical removal of the spinal cord tumor diagnosed as ependymoma. The neurological deficits improved significantly.
