Síndrome opercular o síndrome perisilviano / Operculum syndrome or perisylvian syndrome

El interés de los autores es llamar la atención sobre el síndrome opercular, y estimular con ello su identificación en la práctica neuropediátrica. Se realizó una búsqueda en PubMed desde febrero de 2005 hasta septiembre de 2010, y se comentaron los artículos que, a consideración de los autores, mostraban los diferentes aspectos del concepto, historia, características clínicas, causas, así como del diagnóstico, evolución y pronóstico. El síndrome opercular puede ser de causa congénita o adquirida; en los adultos es más frecuente por infarto cerebral opercular bilateral, no así en los niños, en los que se puede presentar por diferentes causas, desde trastornos de la migración neuroblástica, hasta en la epilepsia. En niños epilépticos se debe estar atento a su evolución, ya que tanto por el tipo de epilepsia o síndrome epiléptico, como por la medicación antiepiléptica usada, puede presentarse este síndrome, teniendo una gran significación su identificación rápida y tratamiento adecuado

The interest of authors is to attract attention on operculum syndrome and thus to stimulate its identification in the neuropediatric practice. A search in PubMed from February, 2005 to September, 2010 was made commenting on papers that according authors showed the different features of concept, history, clinical features, causes, as well as diagnosis, evolution and prognosis. The operculum syndrome may be congenital or acquired; ion adults is more frequent by bilateral operculum cerebral infarction, but not in children in whom it may be present by different causes, from neuroblast migration to epilepsy. In the case of epileptic children it is necessary to pay attention to its course since due to the type of epilepsy or epileptic syndrome or due to antiepileptic drug used, this syndrome may be present, considering very much its fast identification and appropriate treatment

Eating Reflex Seizures in a Patient with Congenital Bilateral Perisylvian Syndrome

We report a young man with congenital bilateral perisylvian syndrome (CBPS), who showed eating reflex seizures (ERS). His ERS were related to the taste of foods. The subtracted ictal SPECT co-registered to MRI (SISCOM) revealed the hyperperfusion in the insula as well as the subcortical nuclei and brainstem. The ERS in CBPS may be partially related with the taste function of the insula and SISCOM may be helpful for the localization of the epileptogenic foci in ERS.

Congenital bilateral perisylvian syndrome:a case report / 北京大学学报(医学版)

Congenital bilateral perisylvian syndrome(CBPS) is rare in literature,especially in China.In this article,we report the clinical and treatment of a patient with CBPS and discuss its mechanism,clinical features and therapy.This patient was a 28-year-old man.His main clinical features were pseudobulbar palsy,cognitive deficits and intractable epilepsy.MRI shows bilateral thickening of the cortex around the sylvian fissures which were deeper than normal and polymicrogyria.The electroencephalogram demonstrated slow spike in right temporal lobe and left frontal lobe.Rhythmal 4 Hz ? waves exist in left frontal and parietal lobe.As the epilepsy was poorly controlled by antiepileptic,section of the corpus callosum was carried out.After callosotomy,there was pronounced seizure reduction and intelligence development improvement.CBPS is characterized by pseudobulbar palsy,cognitive deficits,and bilateral perisylvian abnormalities in imaging studies.If intractable epilepsy is combined,callosotomy may be effective.

Congenital bilateral perisylvian syndrome: analysis of the first four reported Korean patients

The advent of MRI technique has enabled the diagnosis of neuronal migration disorders(NMD) and made it possible to make "in vivo" diagnosis. Congenital bilateral perisylvian syndrome(CBPS) is a recently described disease identify characterized by pseudobulbar palsy, epilepsy, mental retardation, and migration disorders in the bilateral perisylvian area. We have identified four CBPS patients based on neuroimaging and dysarthria patterns among the candidates for epilepsy surgery. All the patients had orofacial diplegia and variable degrees of mental retardation. In the spectrographic analysis of dysarthria, the loss of specific characteristics of formants of vowels and increment of noise in the high frequency formants were observed. Epilepsy was present in all, but only one patient showed intractable seizure requiring surgical intervention. MRI was most helpful in identifying NMD and polymicrogyria in both centroparietal areas in this context. Great alertness is needed to identify this disorder to determine the etiology of epilepsy and dysarthria of uncertain origin.
