Craniopharyngiomas are benign, partly cystic epithelial tumors that account for 5-13% of all intracranial tumors and 50% of all suprasellar masses in children. They pose several challenges to the neuroradiologist. This paper aims to focus on the main issues regarding the neuroradiological diagnosis and follow-up after treatment. Topics include (i) the imaging modalities (i.e., CT and MRI) utilized in the diagnostic workup; (ii) the neuroradiological appearance, focusing on calcifications, cystic components, contrast enhancement, and location; (iii) the relationships to adjacent structures, such as the optic chiasm, hypothalamus, third ventricle, and circle of Willis; (iv) the differential diagnosis with other tumoral and non-tumoral entities occurring in the sellar/suprasellar area; and (v) post-treatment imaging issues.

Neonatal inflammation and near-term white matter microstructure in infants born very preterm.
Neuroimage Rep
December 2024
Department of Pediatrics, Division of Developmental-Behavioral Pediatrics, Stanford University, Stanford, CA, USA.
Background: Severe neonatal inflammatory conditions in very preterm infants (VPT: <32 weeks gestational age, GA) are linked to adverse neurodevelopmental outcomes. Differences in white matter (WM) microstructure of the corpus callosum (CC) have been observed at age 6 in VPT children with a history of severe neonatal inflammation. The goal of this study was to determine whether these CC differences can be detected at term-equivalent age using diffusion MRI (dMRI), and whether neonatal inflammation is associated with altered WM in additional tracts implicated in the encephalopathy of prematurity.

Faculty of Medicine, University of Queensland, Brisbane, Queensland, Australia.
Aim: Angiostrongylus cantonensis, the leading cause of eosinophilic meningoencephalitis, is well established in eastern Australia. Prolonged wet weather in Queensland during 2021-2022 coincided with anecdotal reports of increased neuroangiostrongyliasis cases, prompting an evaluation of paediatric cases from 2013 to 2022.
Methods: This retrospective observational study reviewed children (0-16 years) with cerebrospinal fluid (CSF) eosinophilia (≥ 10% of the total CSF leukocyte count) and/or A.
Brain Age Modeling and Cognitive Outcomes in Young Adults With and Without Sickle Cell Anemia.
JAMA Netw Open
January 2025
Department of Neurology, Washington University in St Louis School of Medicine, St Louis, Missouri.
Importance: Both sickle cell anemia (SCA) and socioeconomic status have been associated with altered brain structure and cognitive disability, yet precise mechanisms underlying these associations are unclear.
Objective: To determine whether brains of individuals with and without SCA appear older than chronological age and if brain age modeling using brain age gap (BAG) can estimate cognitive outcomes and mediate the association of socioeconomic status and disease with these outcomes.
Design, Setting, And Participants: In this cross-sectional study of 230 adults with and without SCA, individuals underwent brain magnetic resonance imaging (MRI) and cognitive assessment.
Multidisciplinary, multicenter consensus for the care of patients affected with Sturge-Weber syndrome.

Background: Sturge-Weber Syndrome (SWS) is a rare, sporadic neurocutaneous disorder affecting the skin, brain, and eyes, due to somatic activating mutations in GNAQ or, less commonly, GNA11 gene. It is characterized by at least two of the following features: a facial capillary malformation, leptomeningeal vascular malformation, and ocular involvement. The spectrum of clinical manifestations includes headache, seizures, stroke-like events, intellectual disability, glaucoma, facial asymmetry, gingival hyperplasia, etc.

We present the case of a 15-year-old girl with new-onset psychosis and abnormal white matter activity on neuroimaging, engaging multidisciplinary care between genetics, neurology, psychiatry, and neuropsychology. She functioned well in mainstream education despite below average intellectual functioning. Physical examination findings enabled the diagnosis, and patient improved with joint psychological and behavioral outpatient services.
