An encephalocele is a pathological brain herniation caused by osseous dural defects. Encephaloceles are known to be regions of epileptogenic foci. We describe the case of a 44-year-old woman with refractory epilepsy associated with a frontal skull base encephalocele. Epilepsy surgery for encephalocele resection was performed; however, the epilepsy was refractory. A second epilepsy surgery for frontal lobectomy using intraoperative electroencephalography was required to achieve adequate seizure control. Previous reports have shown that only encephalocele resection can result in good seizure control, and refractory epilepsy due to frontal lobe encephalocele has rarely been reported. To the best of our knowledge, this is the first report of frontal encephalocele plus epilepsy in which good seizure control using only encephalocele resection was difficult to achieve. Herein, we describe the possible mechanisms of encephalocele plus epilepsy and the surgical strategy for refractory epilepsy with encephalocele, including a literature review.

Seizure outcomes after resection of temporal encephalocele in patients with drug-resistant epilepsy: A systematic review and meta-analysis.
Epilepsia

Department of Neurology, The University of Alabama at Birmingham, Birmingham, Alabama, USA.
Objective: Temporal encephaloceles (TEs) are seen in patients with drug-resistant epilepsy (DRE); yet they are also common incidental findings. Variability in institutional pre-surgical epilepsy practices and interpretation of epileptogenic network localization contributes to bias in existing epilepsy cohorts with TE, and therefore the relevance of TE in DRE remains controversial. We sought to estimate effect sizes and sample sizes necessary to demonstrate clinically relevant improvements in seizure outcome with different surgical approaches.

Article Synopsis
- * Effective treatment for drug-resistant epilepsy is often surgical, relying heavily on imaging to identify abnormalities, though TEs are frequently missed on standard scans.
- * This study explored a voxel-based morphometry (VBM) method to detect TEs in MRI scans, comparing its effectiveness to that of experienced neuroradiologists and epileptologists, revealing that VBM showed lower sensitivity and specificity but could still aid in improving detection and surgical outcomes.
Temporal lobe encephaloceles: Electro-clinical characteristics and seizure outcome after tailored lesionectomy.
Epilepsy Behav
November 2024
Epilepsy Center, Neurological Institute, Cleveland Clinic, Cleveland, OH, USA.
Article Synopsis
- The study investigated how to manage patients with medically resistant epilepsy caused by temporal encephaloceles, focusing on the importance of ancillary testing before surgery to improve surgical outcomes.
- Researchers analyzed medical records from the Cleveland Clinic over two decades, specifically looking at patients who had surgery for drug-resistant temporal lobe epilepsy linked to encephaloceles.
- Results showed that 63% of the 19 patients had successful seizure control one year post-surgery, with detailed patterns of seizure activity revealed through advanced EEG evaluations, indicating a need for personalized surgical strategies.

Department of Neurosurgery, Corewell Health William Beaumont University Hospital Neuroscience Center, Royal Oak, Michigan, USA.
Article Synopsis
- Temporal lobe encephaloceles (TLEN) might cause temporal lobe epilepsy (TLE), and doctors are figuring out the best surgery to treat it.
- A study looked at nine patients with TLE caused by TLEN who had a special test called SEEG to find where their seizures started in the brain.
- Results showed that many patients had successful surgery, with some becoming seizure-free, but seizure activity can happen in areas beyond just the TLEN.
Biallelic TXNDC15 variants associated with Joubert syndrome-related molar tooth sign and forebrain malformation.

TXNDC15 encodes thioredoxin domain-containing protein 15, a protein disulfide isomerase that plays a role in ciliogenesis. Biallelic TXNDC15 variants have been reported in six individuals of Meckel syndrome (MKS) with perinatal lethal phenotypes, but have not been reported in patients with Joubert syndrome (JS). Here, we describe a 1-year-old female patient with compound heterozygous TXNDC15 variants demonstrating cerebellar vermis hypoplasia with the molar tooth sign, mild holoprosencephaly, and cortical abnormalities.
