Rasmussen syndrome and long-term response to thalidomide.

We report a 13-year-old female who experienced symptoms and signs of Rasmussen encephalitis for the first time at the age of 5 years. Various therapeutic procedures, including conventional and new antiepileptic drugs, steroids, immunoglobulin, plasma exchanges, and partial hemispherectomy, were applied, but their results were unsatisfactory. During one of the exacerbations, when the patient's life was endangered, thalidomide was administered.
