There are variations among adults and children regarding the incidence, molecular drivers and response to treatment of specific challenges. Standard tools used during surgery—like frozen section analysis and fluorescence-guided surgery (FGS) are helpful. But, they are limited by sampling error, issue of processing time and fluorescence specificity. This is especially true for infiltrative margins. Stimulated Raman histology (SRH) has recently been developed as a non-invasive imaging technique for fresh tissue based on intrinsic vibrational contrast to generate H&amp;E-like images, which can be used in near-real-time in neurosurgery. This analysis provides an overview of existing studies on the safety of adult and paediatric glioma surgery. To begin with, we will summarise the epidemiological and molecular differences between the adult-type and paediatric-type diffuse gliomas and look at how these differences shape our intraoperative diagnostic needs. The reported SRH performance across age groups, including its ability to distinguish tumour from non-neoplastic brain, assess margins and support safe extent of resection when tissue is limited, as is often the case in paediatric procedures. An assessment is made of how helpful SRH frozen section FGS neuronavigation intraoperative MRI confocal endomicroscopy is. In conclusion, we review key technological, biological, workflow and regulatory limitations, including concerns regarding data and AI generalisability, and highlight future directions, including paediatric-specific SRH–AI models and multimodal integration. In summary, comparative evidence suggests SRH is a profound bridge for precision age-adapted intraoperative neuropathology in gliomas.</div></div>","PeriodicalId":38138,"journal":{"name":"Interdisciplinary Neurosurgery: Advanced Techniques and Case Management","volume":"43 ","pages":"Article 102188"},"PeriodicalIF":0.5,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146037628","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
