Contrast Leakage Patterns from Dynamic Susceptibility Contrast Perfusion MRI in the Grading of Primary Pediatric Brain Tumors [PDF]

, 2016
BACKGROUND AND PURPOSE: The pattern of contrast leakage from DSC tissue signal intensity time curves have shown utility in distinguishing adult brain neoplasms, but has limited description in the literature for pediatric brain tumors. The purpose of this

Nutrition Support Interventions for Children and Young People Treated for Osteosarcoma: A Scoping Review

Journal of Human Nutrition and Dietetics, Volume 38, Issue 6, December 2025.
Whilst a range of nutrition support interventions for those undergoing osteosarcoma treatment has been studied and interest is growing, the evidence is fragmented, methodologically weak and indicates wide variation in clinical practice. We identify priority research needed to establish evidence‐based clinical practice guidance.

Tissue metabolite profiles for the characterisation of paediatric cerebellar tumours

Scientific Reports, 2018
Paediatric brain tumors are becoming well characterized due to large genomic and epigenomic studies. Metabolomics is a powerful analytical approach aiding in the characterization of tumors.

Diffuse spinal leptomeningeal spread of a pilocytic astrocytoma in a 3-year-old child

Clinics and Practice, 2016
Pilocytic astrocytomas correspond to lowgrade gliomas and therefore metastasize exceedingly rare. However, pilocytic astrocytomas are able to and leptomeningeal dissemination may be seen. What are the treatment options of these cases?

Propionic Acidemia: Gray Matter Disease Meets Subcortical Leukodystrophy

Journal of Inherited Metabolic Disease, Volume 48, Issue 6, November 2025.
ABSTRACT Imaging literature on propionic acidemia (PA) is predominantly concerned with deep gray matter changes. In order to investigate the spectrum and patterns of MRI changes, 45 MRI scans of 13 patients (0.31–33.2 years) were systematically analyzed. Deep and cortical gray matter changes were associated with acute metabolic decompensation. Striatum

Whole-genome sequencing identifies genetic alterations in pediatric low-grade gliomas [PDF]

, 2013
The most common pediatric brain tumors are low-grade gliomas (LGGs). We used whole-genome sequencing to identify multiple new genetic alterations involving BRAF, RAF1, FGFR1, MYB, MYBL1 and genes with histone-related functions, including H3F3A and ATRX ...
