Pediatric Diffuse Low-Grade Gliomas: Radiology, Symptoms, Treatment, and Molecular Pathways

Pediatric diffuse low-grade gliomas (LGGs) are heterogeneous group of central nervous system tumors that typically exhibit a relatively benign clinical course. These tumors represent a unique classification in pediatric neuro-oncology, distinct from adult counterparts in terms of biological behavior, molecular pathways, and clinical presentation. The evolving World Health Organization classification system has increasingly relied on combination of histopathologic, genetic, and radiologic criteria to define and distinguish among pediatric glioma subtypes. This article aims to synthesize current knowledge regarding the clinical, molecular, and radiologic features of these pediatric diffuse LGGs and highlights the nuances in diagnosis, treatment approaches, and prognostic outlook.
