Magnetoencephalography (MEG) is a useful non-invasive technique for presurgical evaluation of focal cortical dysplasia patients. We aimed at clarifying the precise spatial relationship between the spiking volume determined with MEG, the seizure onset zone and the lesional volume in patients with focal cortical dysplasia. We studied the spatial relationships between the MEG spiking volume determ...

BACKGROUND AND PURPOSE Malformation of cortical development (MCD) is a well-known cause of drug-resistant epilepsy and focal cortical dysplasia (FCD) is the most common neuropathological finding in surgical specimens from drug-resistant epilepsy patients. Palmini's classification proposed in 2004 is now widely used to categorize FCD. Recently, however, Blumcke et al. recommended a new system fo...

We have generated an experimental 'double-hit' model of chronic epilepsy to recapitulate the co-existence of abnormal cortical structure and frequently recurrent seizures as observed in human focal cortical dysplasia. We induced cortical malformations by exposing rats prenatally to methylazoxymethanol acetate and triggered status epilepticus and recurrent seizures in adult methylazoxymethanol a...

Focal cortical dysplasias (FCDs), initially thought to be rare, are a common cause of drugrefractory epilepsy in both children and adults. Successful resection and subsequent characterization of FCDs was first described by Taylor et al. in 1971 from pathological specimens obtained in patients treated for intractable temporal lobe epilepsy (Tassi, et al.,2001; Becker, et al.,2002; Tassi, et al.,...

A distinctive scalp electroencephalographic (EEG) pattern of focal fast rhythmic epileptiform discharges (FREDs) in a 23-year-old man with symptomatic localization related epilepsy is presented. Magnetic resonance imaging (MRI) of the brain revealed cortical dysplasia over the right temporal region where the peculiar EEG abnormality was detected. We suggest that this characteristic EEG pattern ...

Cone-beam computed tomography (CBCT) provides images without overlapping anatomical structures, which is important for the diagnosis and assessment of florid cemento-osseous dysplasia. This fibro-osseous lesion that affects alveolar process compromising teeth’ pulp vitality usually asymptomatic, bone expansion, cortical disruption, root resorption are uncommon. Due to its avascular characterist...

Focal cortical dysplasia (FCD) is one of the most common epileptogenic lesions associated with development malformations. However, accurate detection FCD relies on radiologist professionalism, and in many cases, lesion could be missed. In this work, we solve problem automatic identification magnetic resonance images (MRI). For task, improve recent methods Deep Learning-based apply it for a data...

Little documentation of the correlation between MR imaging findings in isolated cerebellar cortical dysplasia (CCD) and its neuropathologic characteristics exists in the recent literature. We documented a postmortem neuropathologic study of a clinically and radiologically well-documented case of CCD in a neonate with severe hypotonia and status epilepticus. MR imaging revealed a global vermian ...

Kabuki syndrome (KS) comprises a unique facial pattern with large palpebral fissures, malar flattening and everted lower eyelids, postnatal growth deficiency, skeletal anomalies, dermatoglyphic abnormalities, and mental retardation. Visceral anomalies such as congenital heart defects and urinary tract anomalies have also been reported.[1] KS was described independently by Niikawa et al.[2] and ...
