Thirteen @entity1 affected by @entity6788 were observed in the Pediatric Section of the Institute of Neurosurgery of the Catholic University of Rome in the last six years. Nine of them were operated because of an intractable @entity302 . Seven were males and 2 females; the age at operation ranged between 7 months and 11 years (mean: three years and five months); the follow-up period varied between 1 and 6 years (mean 3 years and 10 months). All the @entity1 had a clinical history of daily @entity302 not responsive to medical treatment; all of them presented with severely delayed @entity1155 development. At neurological examination, six @entity1 showed a @entity51 of variable severity contralateral to the affected hemisphere and two @entity1 a severe @entity10492 . The remaining @entity1 did not present with @entity51 . In all the cases the diagnosis had been obtained by CT scan and MRI. One of the cerebral hemispheres was abnormally enlarged with associated dilation of the lateral cerebral ventricle. The cortical architecture was obviously deranged with several areas of @entity3664 of the gray substance suggesting an alteration of the neuronal cell migration. All the @entity1 underwent an extrathalamocaudato hemispherectomy. A post-operative ventriculo-peritoneal shunt was required in two cases. There were neither operative, nor late deaths. A dramatic reduction in the frequency and severity of @entity302 was observed in all but one of the @entity1 of the series.(ABSTRACT TRUNCATED AT 250 WORDS)
