Management of Malignant Meningiomas

چکیده
Meningiomas are brain tumors that originate from arachnoid cap cells. They account for about one third of all brain tumors (CBTRUS, 2011), and their incidence increases with age. There are many histological subtypes of meningioma and they differ in their level of malignant behavior. The most commonly used World Health Organization (WHO) scheme (see 2.1) classifies them in three grades, which have distinct prognostic properties.

Management of benign and aggressive intracranial meningiomas.
Usually considered benign tumors, meningiomas can display aggressive behavior characterized by multiple recurrences and invasion of the brain, dura, and adjacent bone. The aggressive or malignant phenotype is difficult to characterize due to the broad spectrum of behaviors exhibited by meningiomas. Recent classification schemes based on features of anaplasia rather than histopathology have been...

متن کاملDNA Methylation in the Malignant Transformation of Meningiomas
Meningiomas are central nervous system tumors that originate from the meningeal coverings of the brain and spinal cord. Most meningiomas are pathologically benign or atypical, but 3-5% display malignant features. Despite previous studies on benign and atypical meningiomas, the key molecular pathways involved in malignant transformation remain to be determined, as does the extent of epigenetic a...
متن کاملCorrelation of histopathologic classification with proliferative activity and DNA ploidy in 120 intracranial meningiomas, with special reference to atypical meningioma.
Histologic classification of 120 meningiomas was correlated with their proliferative fraction and DNA ploidy using immunohistochemistry and flow cytometry to differentiate histologically atypical meningiomas from benign ones. Histologically, the 120 meningiomas included 101 benign (43 meningotheliomatous, 40 transitional, 11 fibroblastic, 2 secretory, 2 microcystic, 2 angiomatous, and 1 psammom...
