We report on a 64 year-old woman presenting with Epilepsia Partialis Continua (EPC) affecting the left hand since the age of 24 without neurological deficit. Structural MRI showed a region of focal cortical dysplasia (FCD) over the right central gyrus and lesions in the mesial frontal and occipital cortex secondary to perinatal hypoxic injury. Ictal spike haemodynamic mapping using simultaneous EEG-fMRI revealed significant BOLD signal changes prominent in the region of FCD (larger cluster), occipital cortex (global statistical maximum), prefrontal cortex and cerebellum. The cluster over FCD was in good agreement with the result of EEG source analysis. Our findings provide an interesting illustration of the ability of EEG-fMRI to reveal epileptogenic networks confirming the intrinsic epileptogenic properties of dysplastic neurons.

The authors report a rare case of a 58-year-old female with mild right-sided hemifacial spasms and eyelid myokymia and a concomitant high-grade glial mass. This report outlines the clinical presentation, diagnostic approach, and management of right hemifacial spasms and eyelid myokymia. The patient had a 5-month history of gradually worsening right hemifacial spams accompanied by mild right lower eyelid twitching.

Rasmussen encephalitis (RE) is a rare and progressive form of chronic encephalitis that typically affects one hemisphere of the brain and primarily occurs in pediatric individuals. The current study aims to narratively review the literature about RE, including historical information, pathophysiology, and management of this condition. RE often occurs in individuals with normal development, and it is estimated that only a few new cases are identified each year in epilepsy centers.

Focal status epilepticus, particularly the motor variant of epilepsia partialis continua (EPC), is a rare condition characterized by near-continuous, chronic focal motor seizures, and associated with poor outcomes. Medications, including anesthetics, are often unsuccessful. Surgical resection can result in motor deficits.

Introduction: Epilepsia Partialis Continua (EPC) is a challenging condition in which repetitive transcranial magnetic stimulation (rTMS) can induce a neuromodulation effect of potential diagnostic and therapeutic value.
Methods: A comprehensive literature search was conducted using Pubmed and Web of Science databases to identify cases of EPC who underwent rTMS, including children and adults. Additionally, we present two patients from our centre who underwent rTMS at a low frequency (0.
