Prognostic factors for progression in atypical meningioma

Abstract

In patients with postoperative residual atypical meningiomas, by using volumetric instead of linear measurements in follow-up imaging studies, the authors detected disease progression earlier. By using this approach, treatment for recurrent disease can be instituted promptly with potentially better tumor control and less toxicity due to smaller volume of residual disease.
