We report six cases of meningio-angiomatosis, a disorder of the cerebral cortex of probable malformative origin frequently associated with neurofibromatosis and either asymptomatic or associated with a seizure disorder. The patients, three males and three females, ranged from 10 to 70 years of age at diagnosis. The lesion was an incidental autopsy finding in two patients; four subjects had a seizure disorder which improved following surgical resection of the cortical lesion. In five instances… 
Histopathological study of five cases with sporadic meningioangiomatosis
Findings indicate that meningioangiomatosis lesions show a wide range of clinicopathological features, making diagnosis difficult, and it is important to make a correct diagnosis in order to avoid further aggressive treatment.
Meningioangiomatosis: a case report and review of the literature.
The present case further illustrates the difficulty in identifying an exact histogenetic cell and probably reflects an origin from a primitive perivascular mesenchymal cell.
Meningioangiomatosis in a patient without von Recklinghausen' disease
The case of a 9-year-old boy with a 6-year history of temporal lobe epilepsy is reported, where a hyperdense lesion in the region was revealed and typical psammoma bodies were evident throughout the lesion.
Comparison of Meningio-angiomatosis in a Man and a Dog
The comparative histopathologic and immunohistochemical features of meningio-angiomatosis in a young man and a prepubertal dog are reported and a tentative diagnosis of encephalitis was made prior to obtaining the results of cerebrospinal fluid analysis.
Meningioangiomatosis in an otherwise healthy 13 year-old boy: A case report with emphasis on histopathological findings.
A case of an otherwise healthy 13-year-old boy with no family history or stigmata of neurofibromatosis who presented with intractable seizures and MRI revealed a 2x2 cm mass lesion in the frontal lobe, which is typical for diagnosis of meningioangiomatosis.
Meningioangiomatosis. A comprehensive analysis of clinical and laboratory features.
Only 43% of patients with MA became seizure-free postoperatively compared with 68% previously reported, and >70% of the authors' patients and those in the literature continued to require antiepileptic drugs, which suggests a less optimistic postoperative outcome than previously recognized.
Scrape Cytology of Meningioangiomatosis
Meningioangiomatosis is a lesion characterized by linear capillaries, meningothelial cells and neurons, some exhibiting nuclear atypia that can lead to an erroneous diagnosis of more common conditions, such as meningioma and anaplastic astrocytoma.
Meningio-angiomatosis in a Dog
It is believed that the leptomeningeal plaque in this dog represents a congenital vascular malformation with fibrosis, which is analogous to meningio-angiomatosis of man, and this paper documents a case of canine MA, the first report of MA in the dog.
Meningioangiomatosis Without Neurofibromatosis Type 2
The patient was a 37 year-old man with a long history of frontal headache who underwent cerebral MRI that showed hypointense lesion in the right frontal lobe with heterogeneous contrast enhancement after gadolinium administration, and a right pterional approach with a supraorbital craniotomy was performed.
Cerebral angiofibroma: case report.
Cerebral and meningeal fibromas are rare neoplasms that differ from solitary fibrous tumors and fibrous meningiomas and it is possible that some nodular brain tumors that were previously described as meningioangiomatosis could be reclassified as cerebral orMeningeal angiofibromas.
