Calcifying pseudoneoplasms of the neuraxis (CAPNON) are rare lesions of the central nervous system. To date, about 60 cases have been reported in literature. We present a case that had the peculiarity to occur in a pregnant woman. At 32 weeks of gestation, a 26-year-old woman was hospitalized to explore nocturnal epigastralgia. During the hospitalisation, the patient presented generalised seizures. As an eclampsia had been suspected, a caesarean delivery was performed. Post-operatively, the patient harboured memory disorders and neuro-imaging explorations were done...

BACKGROUND: We report the surgical management of a lesional drug-resistant epilepsy caused by a meningioangiomatosis associated with a type IIIc focal cortical dysplasia located in the left supplementary motor area in a young male patient. CASE DESCRIPTION: A first anatomically based partial surgical resection was performed on an 11-year-old under general anesthesia without intraoperative mapping, which allowed for postoperative seizure control (Engel IA) for 6 years...

Meningioangiomatosis (MA) is a rare benign, hamartomatous lesion within the leptomeninges and cerebral cortex. Three percent of intractable epileptic patients with tumor develop MA. It may be accompanied with neurofibromatosis type II, or it may occur sporadically. Three patients, age range of 2-16 years old, presented with episodes of seizure. The patients demonstrated no family history or stigmata of neurofibromatosis type II. Electroencephalogram (EEG) was unremarkable for epileptiform activity. Magnetic resonance imaging (MRI) revealed enhancing lesions within the frontal gyrus, the anterior cingulate gyrus, and the parietal lobe...

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...

An intra-axial tumor measuring about 4 cm was excised from the right temporal lobe of a 35-year-old woman, who had a past history of resection of craniopharyngioma and postoperative radiation 21 years earlier. The tumor involved both the cortex and white matter, but was not attached to the dura mater. It consisted of a dense, interlacing, fascicular proliferation of atypical fibroblastic cells and was associated with an extensive, lace-like, desmoplastic change mainly involving the perivascular region around the tumor and overlying the subarachnoid space...

OBJECTIVE: To investigate the clinicopathologic characteristics of meningioangiomatosis (MA). METHODS: Five cases of MA were evaluated morphologically by HE and immunohistochemistry on formalin-fixed paraffin-embedded tissue. Clinical information was also obtained. The literature was reviewed. The clinical pathology and biological behavior of MA were discussed. RESULTS: Five cases of MA were reported, arising in three males and two females, with an age range of 16 to 26 years at diagnosis...

BACKGROUND: Meningioangiomatosis (MA) is a rare meningiovascular malformation or hamartomatous lesion in the central nervous system. Radiographic findings of MA may show a variety of characteristics according to different histological components. We present three cases of sporadic MA with different imaging appearances in an attempt to identify specific imaging characteristics. CASE PRESENTATION: In case 1, an irregular hyperdense solid mass was localized in the left middle cranial fossa, demonstrating low and equal signal intensity on T1-weighted imaging (T1WI; TR/TE 2,048...

BACKGROUND: Meningioangiomatosis (MA) is a rare cerebral lesion. Sporadic MA occasionally combines with meningioma (MA-M). The aim of the present study was to clarify whether MA-M and pure MA have clinical differences and to determine risk factors for unsatisfactory seizure outcomes in sporadic MA. METHODS: We reported 14 sporadic MA cases in our center and conducted a literature review. We compared the demographic, clinical, imaging, electrophysiological and pathological features and surgical outcomes...

The neuroradiological features of meningioangiomatosis (MA) are non-specific. We report a young man with sporadic MA. The plain computerized tomography (CT) demonstrated a deep located right cystic lesion without calcification. On magnetic resonance imaging, the cystic mass lesion was confirmed with a mural nodule with significant enhancement on contrast-enhanced images.

Meningioangiomatosis is a rare, benign, developmental, or hamartomatous lesion which may involve the leptomeninges and underlying brain parenchyma. Histologically, meningioangiomatosis is marked by a proliferation of blood vessels in the parenchyma, rimmed by collars of spindled meningothelial cells. There are anecdotal reports of an association of meningioangiomatosis with focal cortical dysplasia. We retrospectively analyzed the clinical, histopathologic, and treatment outcomes of 16 patients with a diagnosis of meningioangiomatosis, specifically investigating these cases for evidence of adjacent focal cortical dysplasia...

"Solitary" meningioangiomatosis (MA) is a rare, benign, hamartomatous lesion of the cerebral cortex and frequently leads to epilepsy. However, the source of the epileptogenicity in meningioangiomatosis remains controversial. We report two surgically-treated meningioangiomatosis cases with medically intractable epilepsy. In both cases, chronic subdural electrocorticogram (ECoG) recordings identified the ictal onset zone on apparently normal cortex, adjacent to and/or above the meningioangiomatosis lesion, not on the meningioangiomatosis lesion itself...

We describe to our knowledge the first case of meningioangiomatosis identified in a second trimester fetus. A 30-year-old pregnant woman was attended at our hospital for a second-trimester ultrasound screening scan. With a diagnosis of partial agenesis of the corpus callosum, the parents requested termination of the pregnancy. At autopsy, frontal serial sections of the fetal brain disclosed a short corpus callosum that lacked the posterior splenium, confirming the sonographic diagnosis. At close inspection, a slight bilateral hardening of both medial aspects of the frontal lobes and anterior genu of the corpus callosum was found associated with meningeal adhesion between both frontal lobes...

BACKGROUND: Meningioangiomatosis (MA) is a rare hamartomatous lesion. Only six cases of cystic MA have been reported in the literature. CASE PRESENTATION: We present a case of multicystic MA. A 21-year-old woman without any stigmata of neurofibromatosis type 2 presented with intractable seizures since 10 years. Brain magnetic resonance imaging revealed a well-defined, multicystic mass with heterogeneous signal intensity in the right temporal lobe. The patient underwent resection of the lesion and of the epileptogenic cortex under intraoperative electrocorticography (ECoG) assistance...

INTRODUCTION: Meningioangiomatosis (MA) is a rare benign cerebral lesion. We aimed to evaluate the CT and MR features of sporadic MA, with a focus on the correlation between imaging and histopathologic findings. METHODS: CT (n = 7) and MR (n = 8) images of eight patients (6 men and 2 women; mean age, 12.8 years; range, 4-22 years) with pathologically proven MA were retrospectively reviewed. After dividing the MA lesions according to their distribution into cortical and subcortical white matter components, the morphologic characteristics were analyzed and correlated with histopathologic findings in seven patients...
