[Rasmussen syndrome--indications for surgical treatment of refractory epilepsy: report of two cases]

Presentation of two cases of children with Rasmussen's encephalitis, treated by functional hemispherectomy. Two boys aged 4 and 6, with a typical clinical course, typical findings in CT and MRI scans and characteristic pathologic changes in brain specimens. In both cases was performed functional hemispherectomy.

Immediate cessation of seizures in the immediate postoperative period (Engel class I and II). Later, in a 4-months' follow-up period, a worthwhile improvement in psychomotor development and social functioning was noted. Up-to date opinions published in available literature, related to pathogenesis and treatment modalities of Rasmussen's encephalitis are presented.

1) Rasmussen's encephalitis is a definite nosologic entity, leading to drug-resistant epilepsy and a progressive psychomotor deterioration; 2) functional hemispherectomy is a viable alternative, which should be considered in the treatment of Rasmussen's encephalitis; 3) Functional; hemispherectomy, in spite of it's aggressiveness, is a relatively safe procedure; 4) in the follow-up time of 4 months, the results are promising.
