Evaluating arteriovenous malformation and diffuse glioma: The role of arterial spin labeling MRI in complex neuroimaging—A case report

In this case report, we explore the utility of arterial spin labeling (ASL) MRI in a complex neuroimaging scenario featuring concurrent arteriovenous malformation (AVM) and a non-enhancing glioma in a 38-year old male. The report delves into the integration of ASL MRI with standard neuroimaging techniques, highlighting its role in providing detailed hemodynamic insights, particularly in characterizing the AVM and assessing the glioma's perfusion pattern. The case presents a diagnostic challenge due to the coexistence of these pathologies and discusses the implications of these findings in light of the evolving WHO brain tumor classification, which emphasizes the importance of molecular markers alongside histopathology. The report emphasizes the need for careful interpretation of advanced imaging in the absence of histopathological confirmation and advocates for a multidisciplinary approach in the management of such cases, underscoring the significance of ongoing research in harmonizing imaging techniques with molecular diagnostics
