Imaging-Based Score for Predicting Higher-Grade Meningiomas

Introduction: Predicting whether an intracranial meningioma will be higher grade based on preoperative imaging studies remains challenging. While various imaging characteristics have been previously found in the literature to correlate with higher grade lesions, such as presence of edema, heterogeneous enhancement, and shape irregularity, no single finding has been shown to have a high positive predictive value for higher grade meningiomas.
