MULTIPLE sclerosis often simulates a brain tumor, but the history and the impossibility of explaining the symptoms and signs on the basis of a single lesion usually establish the diagnosis. It is known that electroencephalograms show a tendency to slow focal activity in this disease, but the relatively few reports of air studies in multiple sclerosis have revealed only minor changes, all described as being due to diffuse or patchy cerebral atrophy, with secondary minor enlargement of the ventricular system.
REPORT OF A CASE
The present case illustrates a ventricular displacement in multiple sclerosis entirely compatible with the diagnosis of a brain tumor.D.
