Meningiomas are the most frequent primary brain tumors, accounting for ∼37% of central nervous systems tumors. Despite being largely benign, clinicians frequently face difficult treatment decisions in cases with complex morphology or localisation, near vital brain structures such as the optic nerve or in the case of incidental tumors. Here, we review current concepts of diagnosis, treatment and follow-up with clinical decision-making informed by multimodal imaging, histology, and molecular biology.
