Tumefactive demyelinating lesions
Tumefactive demyelinating lesions can present with motor, cognitive, cerebellar, and brainstem dysfunction, as well as headache, seizures, aphasia, cortical sensory loss, or psychosis. They are more likely to cause cortical signs, such as altered mental status and visual field deficits, than typical CNS demyelinating lesions. Two-thirds of patients with this condition subsequently develop multiple sclerosis.
