“…CC is especially effective for seizures which are generalized and result in fall injuries, such as tonic and atonic seizures [65]. CC has been used to lateralize a seizure focus that appeared bilateral on scalp and intracranial monitoring for definitive epilepsy surgery when focal semiology was suspected [66].…”

Many providers feel uncomfortable with the recognition of epileptic seizures, the diagnosis and classification of epilepsy syndromes, and initial treatments to offer to patients with epilepsy. Available therapies for children with epilepsy include medical management with antiseizure medications, trial of the ketogenic diet, and evaluation for epilepsy surgeries. This chapter will highlight the diagnostic criteria for epilepsy, common epilepsy syndromes according to the recent updated International League Against Epilepsy (ILAE) Classification, and when to refer to an epilepsy center for specialized treatments if not readily available such as the ketogenic diet, phase 1 presurgical evaluation, and epilepsy surgery. This chapter will also briefly highlight frequent comorbidities with epilepsy such as psychogenic nonepileptic seizures and attention deficit hyperactivity disorder and the challenges related to seizure mimics. This chapter will therefore highlight the diagnosis, workup, and management of both medically responsive epilepsy and drug resistant epilepsy (DRE) as well as its comorbidities. This chapter is a comprehensive review of the literature for the diagnosis and treatment of epilepsy and the author’s experience of practice working at Riley Hospital for Children at Indiana University Health which is a National Association of Epilepsy Centers (NAEC) Level 4 Epilepsy Center.

“…Some items should be included in the evaluation of epileptogenic activity for surgery, including interictal electroencephalogram (iEEG), interictal spect, magnetic resonance imaging (MRI) and age-appropriate neuropsychological/developmental assessment. Some exams, like the intracranial EEG, could indicate a complementar surgery after a callosotomy, because it provides the localization of the correct focus of seizure 53 . Other exams may be useful on this avaliation and should be included in the protocols of seizures foci investigation, like functional MRI and EEG 33 .…”

Introducción: Los pacientes con convulsiones intratables que no son candidatos para la cirugía de resección focal están indicados para un procedimiento quirúrgico paliativo, la callosotomía. Este procedimiento se basa en la hipótesis de que el cuerpo calloso es una importante vía para la propagación interhemisférica de la actividad epiléptica y, para la epilepsia resistente a fármacos. Presenta relativamente baja morbilidad permanente y una eficacia en el control de las convulsiones. Sobre la base de la literatura, la callostomía mejora la calidad de vida de los pacientes que tiene la indicación para realizar este procedimiento, ya que permite reducir la frecuencia de las crisis, ya sean tónica o átona, tónico-clónicas, ausencia o lóbulo frontal crisis parciales complejas. Objetivo: El objetivo de esta revisión de la literatura es discutir los detalles técnicos, modalidades, riesgos, complicaciones, resultados y de pronóstico de callosotomía basado en la revisión crítica de la literatura y la experiencia de los autores. Casuística y Métodos: Se realizó la consulta bibliográfica, utilizando la base de datos MEDLINE, LILACS, SciELO, que utiliza el lenguaje como criterios de selección, la elección de los artículos recientes preferiblemente en portugués, español o Inglés, con el año de publicación superior a 2000. Conclusión: De acuerdo con la experiencia y las referencias del autor, callosotomía es un procedimiento seguro cuando indicado para casos seleccionados y la tasa de éxito es proporcional a la extensión de la resección del cuerpo calloso. A mayor resección puede reducir la frecuencia de las crisis, sin embargo, la morbilidad puede ser también mayor. No hay ningún estudio que compara la estimulación del nervio vago frente a frente callosotomía VNS más callososotomy, lo que sería la futura necesaria para una importante fuente de datos sobre este tema.

“…Surgery is considered when epilepsy is drug-resistant, defined as failure of therapeutic doses of two anticonvulsant medications with unique mechanisms [2,3]. The ideal surgical candidate has a focal epileptogenic zone (EZ) amenable to resection or stereotactic thermal ablation [4]. Lateralizing the EZ in frontal lobe epilepsy is challenging due to secondary bilateral synchrony from commissural connections through the corpus callosum and low spatiotemporal resolution of the scalp electroencephalography (EEG) [4].…”

New onset refractory status epilepticus (NORSE) is an etiologically heterogeneous condition that is associated with high morbidity and mortality. NORSE is often refractory to medical management prompting a workup for epilepsy surgery. Because NORSE remains etiologically elusive in most cases, surgical evaluations are challenging, especially when the epileptogenic zone (EZ) is not easy to lateralize as can be seen in frontal lobe seizures. Lateralizing a frontal lobe EZ may be challenging due to bilateral synchrony from commissural connections through the corpus callosum and low spatiotemporal resolution of the scalp electroencephalography (EEG). We report a pediatric patient with NORSE presenting with focal impaired awareness seizures clustering into super refractory status epilepticus (SRSE). She required surgical intervention for the treatment of her seizures after failing therapeutic doses of antiseizure medications, anesthetic drips, immunomodulation with methylprednisolone, intravenous immunoglobulin and anakinra, and the ketogenic diet. Despite her semiology being focal, the seizures were not well lateralized on scalp EEG and during phase 2 stereo-EEG (sEEG). Anterior magnetic resonance-guided laser interstitial thermal therapy corpus callosotomy (MRgLITT CC) was performed in a multistage surgical approach to successfully lateralize the EZ with a left-lateralized ictal pattern seen after reimplantation of sEEG electrodes. Our case suggests that minimally invasive MRgLITT CC can be successfully used to lateralize an EZ in frontal lobe epilepsy and that epilepsy surgery should be considered in patients with NORSE with SRSE. We also demonstrate that laser interstitial thermal therapy (LITT), while not always resulting in seizure freedom, can sufficiently disrupt a network to abort status epilepticus and lead to seizure improvements.
