Rasmussen encephalitis with ipsilateral brain stem involvement in an adult patient.

Rasmussen encephalitis is a rare unihemispheric inflammatory disease of the brain that leads to intractable seizures, cognitive decline and progressive neurological deficits associated with the affected hemisphere. It predominantly affects children, with the onset in adults having a milder course. Here the case of an adult woman with Rasmussen encephalitis responsive to immunosupression is reported.
