The patient was referred because of multiple epileptic seizures. MRI was performed the next day. To load a higher resolution view, simply click directly on any of the images below. MRI shows multifocal areas of hyperintensity in the subcortical white matter on T2-weighted SE images. Figures 1b, 1c.
Lesions become markedly enhanced with contrast media, indicative of a blood brain barrier defect.
Also, the pons shows a big lesion, which is a typical sign of vasculitis. Under high dosage immunosuppressive therapy, including cortisone and plasmapheresis, the patient soon improved. Follow-up MRI shows complete restitution of the intracerebral changes that took place over 2 months. The blood barrier defect is no longer apparent. Figures 3a, 3b.
