Histopathologic and Molecular Evaluation of Meningioma

This article reviews various aspects of the pathology of these tumors, from their frozen section appearance to the various subtypes a pathologist may come across at the microscope. Special emphasis is placed on the importance of CNS World Health Organization grading by light microscopic means to predict biological behavior of these tumors. Furthermore, relevant literature concerning the potential impact that DNA methylation profiling of these tumors and the possibility that this molecular testing modality might be the next step in refinement of our analysis of meningioma is presented.
