Abstract
Meningioangiomatosis (MAM) remains a poorly understood lesion responsible for epileptic disease. In the past, MAM was primarily described in the context of neurofibromatosis type 2 before being mainly reported sporadically. Moreover, the malformative or tumoral nature is still debated. Because a subset of MAM are associated with meningiomas, some authors argue that MAM corresponds to an infiltration pattern of these tumors. For these reasons, MAM has not been added to the World Health Organization (WHO) Classification of Central Nervous System Tumors as a specific entity. In the present study, we characterized a series of pure MAM (n = 7) and MAM associated with meningiomas (n = 4) using histopathology, immunohistochemistry, genetic (fluorescent in situ and DNA sequencing analyses), and epigenetic (DNA-methylation profiling) data. We evidenced two distinct morphological patterns: MAM with a fibroblastic-like pattern having few lesional cells, and MAM with a more cellular pattern. A subset was associated with the genetic alterations previously reported in meningiomas (such as a KMT2C mutation and a hemizygous deletion of chromosome 22q including the NF2 gene). The DNA-methylation profile, using a t-distributed stochastic neighbor embedding analysis, evidenced that MAM (pure or associated with meningiomas) clustered in a separate group from pediatric meningiomas. The present results seem to suggest that MAM represents a neoplastic lesion and encourage the further study of similar additional series so that it may be included in a future WHO classification.

Abstract
Meningioangiomatosis (MA) is a rare malformation or hamartomatous lesion in the central nervous system, characterized by a plaque-like mass within the leptomeninges and cerebral cortex. An even rarer condition is MA complicated with meningiomas. We herein report a case of meningioma associated with MA that might be erroneously interpreted as a higher-grade lesion or an invasion by preoperative radiologic and postoperative histological examinations.

Abstract
Meningioangiomatosis is a rare benign lesion involving the central nervous system. Radiographic appearance can be highly variable which makes pre-operative diagnosis difficult. In this report, we describe meningioangiomatosis in a previously healthy 17-year-old woman who presented with seizures and continued headache and dizziness. This patient presented with a predominately calcified lesion on imaging and eventually underwent near total resection. Meningioangiomatosis is difficult to preoperatively identify, but is an important consideration as prognosis with surgical resection is typically good.

Abstract
Meningioangiomatosis is regarded as a rare benign hamartomatous condition mostly involving the cerebral cortex and overlying leptomeninges. A strong association of MA with neurofibromatosis type 2 has been documented in published articles. Herein we report a case of an otherwise healthy 13-year-old boy with no family history or stigmata of neurofibromatosis who presented with intractable seizures. MRI revealed a 2x2 cm mass lesion in the frontal lobe. The patient underwent complete surgical resection of the lesion. Although the primary radiologic impression of the lesion was glioma, pathological evaluation of the resected specimen showed mainly proliferation of meningothelial cells and fibroblast-like cells with many thickened blood vessels, which are typical for diagnosis of meningioangiomatosis. After surgical removal of the lesion, the patient is free of seizures.
