Introduction: Cerebral cortical development is a highly complex process influenced by environmental, genetic and functional abnormalities. Hemimegalencephaly (HME) is a rare brain malformation that involves overgrowth of one hemisphere. Clinically macrocephaly, mental retardation, contralateral hemiparesis, hemianopsia and intractable epilepsy may be present. Diagnosis is mainly done with image...
objective proteus syndrome is an extremely rare, sporadic and progressive disorder. we describe a four-month-old male baby with central nervous system manifestations in this article. clinical presentation a four-month-old boy was admitted into our hospital with three tonic - clonic generalized seizure attacks which started from the day before admission. each seizure attack lasted less than 10 m...
We describe two children with complex cortical malformations as well as the typical intracranial manifestations of tuberous sclerosis complex. One child had hemimegalencephaly and the other had extensive focal megalencephaly. These cases are discussed in terms of the current concepts of cortical malformations.
The authors report two cases of Brazilian children with most of the common syndromic features of Proteus syndrome, such as asymmetric overgrowth of tissues, skin abnormalities, hypotonia and mental retardation. In both patients, a refractory epilepsy, compatible with Ohtahara syndrome, as well as hemimegalencephaly, with asymmetric distribution of facial fat, were also diagnosed.
A patient with hemimegalencephaly and intractable epilepsy underwent a preoperative embolic hemispherectomy. A seizure-free interval of 1 year followed the embolization procedure. In addition, the procedure was thought to be beneficial in limiting blood loss during a subsequent surgical hemispherectomy.
