Multinodular and vacuolating neuronal tumors (MVNTs) of the cerebrum are rare, seizure-related, low-grade tumors of the central nervous system that usually affect young adults. First described by Huse et al. in 2013, these neoplasms are usually located within the deep cortical ribbon and the superficial white matter and have a characteristic cytoarchitecture of cells with neuronal and glial differentiation that form multiple nodules with conspicuous vacuolation.

Methods: Surface-based morphometry (SBM) was assessed on 3D T1-weighted images using FreeSurfer image analysis and WM microstructure was studied using Tract-Based Spatial Statistics (TBSS) in 12 AD, 15 LBD, 10 CBS patients, and 10 HC.
Results: Patients with AD, compared with HC, exhibited reduced cortical surface area and volume in the superior frontal, middle frontal, and medial orbitofrontal cortex.
Article Synopsis
- The study focuses on 'children in need' in Greece and their energy balance-related behaviors (EBRBs) related to overweight and obesity, highlighting a lack of existing literature at the European level.
- Seven studies were reviewed, indicating prevalent unhealthy behaviors such as poor diet, inadequate sleep, and high sedentary activity among these children, influenced by factors like low parental education and socioeconomic status.
- The findings aim to inform future research, interventions, and public health policies to better address the needs of this vulnerable population in Greece.
The goal of this paper is to provide a useful desktop reference for the imaging of suspected child abuse with clear, age-specific pathways for appropriate evidence-based imaging and follow-up. We aim to provide a road map for the imaging evaluation and follow-up of this important and vulnerable cohort of patients presenting with signs and symptoms concerning for inflicted injury. As the imaging recommendations differ for children of different ages, we provide a flowchart of the appropriate imaging pathway for infants, toddlers, and older children, which allows ease of selection of which children should undergo skeletal survey, non-contrast computed tomography (CT) brain with 3-dimensional (D) reformats, and magnetic resonance imaging (MRI) of the brain and whole spine.

It discusses various techniques for analyzing brain connectivity and their implications for clinical interventions in neurodevelopmental disorders.
Methods: The principles and applications of independent component analysis and seed-based connectivity analysis in pediatric brain studies are outlined.
