SUMMARY -We describe the case of a 48 year-old man in whom the clinical features, CT and MR scans were suggestive of a brain tumor but, posteriorly, another MRI study, CSF examination and brain biopsy supported the diagnosis of multiple sclerosis. Interestingly, this patient presented parkinsonian features, probably in connection with the underlying disease.KEY WORDS: multiple sclerosis, tumoral form, parkinsonism. The authors report the case of a patient with the tumoral form of MS and parkinsonian features. To the best of our knowlegde, this association has hardly been reported in the current literature.
