Article Synopsis
- - The article discusses a rare finding of atypical pathological features in the brains of patients with drug-resistant epilepsy, revealing a mix of ganglioglioma and focal cortical dysplasia, which hasn't been documented before.
- - Comprehensive tests including histopathological staining and molecular genetic analysis were conducted, and MRI scans showed unusual patterns such as "transmantle" distribution and local alterations in the brain structure.
- - The findings suggest the presence of a new subgroup of gangliogliomas characterized by cellular atypia, indicating a potential link between different types of neuronal-glial tumors that could reshape our understanding of epilepsy-related brain pathology.

Department of Child Health, Dr Soetomo General Academic Hospital, Surabaya, Indonesia.
Epilepsy is a prevalent neurological disorder in children, with 30-35% of cases developing into intractable epilepsy despite appropriate anti-seizure medications (ASMs). Advanced imaging is crucial for early diagnosis, especially in detecting structural causes like gangliogliomas, which are associated with drug-resistant focal epilepsy. We report a 5-year-old boy with recurrent seizures, initially undetected by EEG.

Article Synopsis
- Mesial temporal lobe epilepsy (MTLE), primarily characterized by hippocampal sclerosis (HS), is often linked with rare mutations, specifically in this case concerning the BRAFV600E mutant protein found in neurons.
- A 31-year-old male patient with severe epilepsy showed typical MRI and EEG signs of mesial temporal sclerosis, and surgical analysis revealed altered neuron orientations and specific cell types associated with the mutation, despite their low overall presence.
- The patient's condition improved significantly post-surgery, and findings indicate that understanding the early genetic changes in HS could enhance research on potential early tumors or lesions, suggesting routine mutation screenings in clinical trials for MTLE-HS cases.

Article Synopsis
- The study presents a rare case of pediatric bilateral optic neuropathy and retinopathy linked to autoimmune retinopathy, along with a review of existing literature on similar pediatric cases.* -
- It involves a case report of one original subject and data from five others identified in recent literature, utilizing various diagnostic methods such as imaging, electrophysiologic testing, and autoantibody testing.* -
- Results showed that all subjects had retinal abnormalities, with optic nerve issues in most; three subjects had abnormal electrophysiologic test results, and four exhibited underlying neoplastic disorders.*

Objectives: To elucidate the relationship between DNA methylation profiling (DMP) and pathological diagnosis (PD) in pediatric glial and glioneuronal tumors with B-Raf proto-oncogene, serine/threonine kinase mutations, addressing their diagnostic challenges.
Methods: This retrospective study, conducted in Saudi Arabia, analyzed 47 cases from the Children's Brain Tumor Network online database using scanned images, next-generation sequencing data, and methylation profiles processed using the Heidelberg methylation brain tumor classifiers v12.5 and v12.

Article Synopsis
- Pilocytic astrocytomas (PA) are tumors that have unique features based on where they are located in the brain or spine.
- Doctors face challenges in telling PAs apart from similar tumors, especially in the brain's hemispheric region.
- A study looked at different types of PAs, and found that they often affect kids and can show various patterns in medical tests, highlighting the need for careful examination for accurate diagnosis.

Objective: To investigate the treatment plan and prognosis of children with ocular dyskinesia and hemifacial spasm secondary to pontine tumours adjacent to the fourth ventricle.
Methods: In this retrospective study, the clinical information of 10 consecutively collected children with ocular dyskinesia and hemifacial spasm secondary to pontine tumours adjacent to the fourth ventricle was analyzed. All 10 children underwent pontine tumour resection through a trans-cerebellomedullary fissure approach; 4 children underwent preoperative diffusion tensor imaging scans to determine the relationship between the tumour and facial nerve nucleus, and the other 6 children underwent intraoperative deep electroencephalography (EEG) tumour monitoring, in which the tumour electrical discharge activity of the tumour was recorded.
