Reversible encephalopathy with cerebral vasospasm in a Guillain-Barré syndrome patient treated with intravenous immunoglobulin.
We report a patient with a reversible multifocal encephalopathy that developed 3 days after completion of treatment with intravenous immunoglobulin for Guillain-Barré syndrome. Magnetic resonance imaging showed reversible bioccipital white matter changes, and transcranial Doppler demonstrated transiently increased flow rates in all major cerebral arteries. We conclude that intravenous immunoglobulin therapy caused cerebral arterial vasospasm and a reversible encephalopathy.
