Fulminant form of multiple sclerosis simulating brain tumor: a case with parkinsonian features and pathologic study

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.
