Prediction of High-Grade Histology and Recurrence in Meningiomas Using Routine Preoperative Magnetic Resonance Imaging: A Systematic Review.

摘要: Objective Estimating the risk of recurrence after surgery remains crucial during care patients with meningioma. Numerous studies identified correlations characteristics on routine preoperative magnetic resonance imaging (MRI) postoperative or high-grade histology but showed partially inconclusive results. Methods A systematic review literature was performed about findings MRI and their correlation recurrence. Quality included analyzed using standardized Assessment Diagnostic Accuracy Studies criteria. Results Among 35 included, quality series according to criteria differed widely. Remarkably, variables found be associated were commonly not consistently prognosis vice versa. Correlations tumor size, peritumoral edema contrast-enhancement capsule controversial. In most studies, non-skull base location, cyst formation, heterogenous contrast-enhancement, an irregular shape, disruption tumor/brain border intensity lesion T2-weighted images, calcifications, bone involvement grade II/III histology. Although size usually correlate recurrence, contrast enhancement, MRI, enhancement mostly related progression. Conclusions Several consistent inconsistent identified. are needed provide further clarification, consideration these can help improve estimation therefore in
