“…This finding suggests that hormones may play an important role in the pathogenesis of MA-M. Wiebe et al suggested that the temporal lobe was the most frequently involved in MA [1], while the frontal lobe seemed to be more affected, based on our analysis. Rarely, MA has been documented to occur in the diencephalon [25], in the brain stem [43] and outside the cerebral cortex [54]. In our series, we reported an MA-M lesion (case 3) that was believed to be the first reported MA-M case involving the corpus callosum (Fig.…”

“…Takeshima et al demonstrated that only 25 % of MA cases were associated with NF2, while in the remaining 75 %, it occurred sporadically [72]. Occasionally, MA has been reported to coexist with meningiomas [11,39,54,82], arteriovenous malformations [23], encephaloceles [75], oligodendrogliomas [50], meningeal hemangiopericytomas [39] and focal cortical dysplasia [65]. Among these, MA with meningioma is the most frequent combination.…”

Clinical differences may be caused by the different biological natures. MA-M seems to be a neoplastic lesion, while pure MA seems to be a non-neoplastic lesion. Long-term follow-up is required for MA-M. Because the coexistence of hippocampal sclerosis may explain the poor seizure outcomes of MA located in the temporal lobe, it is important to identify underlying hippocampal sclerosis and to perform complete resection.

“…En caso de ausencia de atipia celular, el patrón de crecimiento perivascular y la presencia de ovillos neurofibrilares en las neuronas del tejido cortical residual 10,22 apoyarían el diagnóstico de MA. También se ha descrito un caso de meningioma intraparenquimatoso bien delimitado del parénquima adyacente y constituido por células que expresaban vimentina y EMA, asociado a MA adyacente con ovillos neurofibrilares en el tejido cortical respetado 23 . Se postuló que el meningioma se originaba a partir de la MA, aunque también podría corresponder a un nódulo hiperplásico de la MA.…”

ResumenLa Meningioangiomatosis (MA) es una lesión benigna intracraneal poco frecuente. La mayoría de los casos son aislados, pero también se han descrito casos asociados a Neurofibromatosis (NF) tipo 2. Los casos asociados a NF suelen ser asintomáticos. Los casos no asociados a NF son sintomáticos, se presentan en niños y adultos jóvenes, y en general afectan a leptomeninge y a corteza cerebral subyacente.En este trabajo se describen 2 casos no asociados a NF en niños de 1 y 7 años de edad, que se manifestaron por crisis, las cuales desaparecieron tras la extirpación de la lesión. Histológicamente las lesiones eran de predominio celular en un caso y de predominio fibro-hialino en el otro.De la revisión de la literatura se concluye que las meningioangiomatosis no asociadas a NF suelen ser lesiones únicas, clínicamente suelen presentarse con crisis convulsivas, y pueden verse asociadas a otras patologías, fundamentalmente a meningiomas.Histológicamente las lesiones corresponden a una proliferación celular de hábito meningotelial que se dispone alrededor de los vasos corticales. A pesar de que todos los casos tienen características comunes, existe un amplio espectro de formas histológicas, que abarca desde casos más celulares hasta casos más fibrosos con calcificaciones. Estas diferencias podrían corresponder a diferentes estadios evolutivos de la lesión. La extirpación de la lesión conlleva la desaparición de los sínto-mas.PALABRAS CLAVE: Corteza cerebral. Hamartoma, Leptomeninge. Meningioangiomatosis. Meningioma. Tumor. Meningioangiomatosis: report of two cases and literature review SummaryMeningioangiomatosis (MA) is a rare benign intracraneal lesion. The majority of cases are sporadic although the association of this lesion with familial neurofibromatosis (NF) type 2 is well known. NF-associated MA may be multifocal and is often asymptomatic and diagnosed at autopsy. Non-associated cases are usually symptomatic, occurs in children and young adults and frequently arise in leptomeninges and underlying cerebral cortex.In the present work, we describe two new non-associated cases of MA in two boys, seven and one year old with seizures that disappeared after surgical excision.Histopathologically, the lesion was predominantly cellular in one case and more fibrous in the other.From the literature review we concluded that sporadic cases present as single lesions which manifest by seizures or persistent headaches. Rarely MA has been described to coexist with meningiomas.Histopathologically IntroducciónLa meningioangiomatosis (MA) es una lesión intracraneal benigna poco frecuente, que suele presentarse en niños

The most important differential diagnosis of meningioma with MA is because the prognosis and evolution of these 2 entities is entirely different 24 .…”

Meningioangiomatosis: clinical-radiological features and surgical outcome

et al. 2010

SummaryMeningioangiomatosis (MA) is a rare, benign neoplastic disorder involving the cortex and leptomeninges, the sporadic form, commonly presents as refractory localization-related epilepsy, but could be asymptomatic especially in older patients. The imaging features may be entirely non-specific. Magnetic Resonance Imaging (MRI) erroneously suggests meningioma, lowgrade tumour or vascular malformations.The pathological findings are characterised by proliferation of meningothelial cells and leptomeningeal vessels and calcifications within the mass. Macroscopically there is dense thickening in the underlying cortex, often in a sharply defined area.In this article we report 3 cases of MA, neither of whom had a familiary history or stigmata of Neurofibromatosis (NF). We discuss and place particular emphasis on the clinical presentation and diagnosis imaging, as well as on the outcome. We also review the literature concerning about the aetiology, pathology findings and imaging features of MA.KEY WORDS: Brain tumor. Histopathology. Meningioangiomatosis. Magnetic resonance imaging. Seizure. Meningioangiomatosis: características clínico-radioló-gicas y resultados quirúrgicos ResumenLa meningioangiomatosis (MA) es un proceso neoplásico benigno raro, que envuelve el córtex y leptomeninges, en su forma esporádica comúnmente se presenta con epilepsia refractaria, en relación a su localización, pero puede ser asintomática, especialmente en adultos mayores. Las características de imagen pueden ser totalmente inespecíficas. Las imágenes de resonancia magnética erróneamente sugieren la presencia de un meningioma, tumores de bajo grado, o malformaciones vasculares.Los hallazgos patológicos se caracterizan por la proliferación de células meningoteliales, vasos leptomeningeos y calcificaciones dentro del tumor. Macroscópicamente se observa un denso engrosamiento en el córtex adyacente, generalmente con un área claramente definida.En este articulo, se describen 3 casos de MA, ninguno de ellos presentaba historia familiar o estigmas de neurofibromatosis (NF). Nosotros realizamos la discusión, haciendo particular énfasis en la presentación clínica y diagnóstico por imágenes, así como en el pronóstico.
