Intraventricular meningioma admixed with choroid plexus papilloma: a rare case report with review of literature (original) (raw)

Ventricular Meningiomas: Surgical Strategies and a New Finding That Suggest an Origin From the Choroid Plexus Epithelium

World Neurosurgery, 2019

BACKGROUND: The aim of this study is to share our experiences on a series of 21 patients with intraventricular meningiomas (IVMs). Histopathologic examinations are reviewed in detail and the cell of origin of IVMs is discussed.-METHODS: We retrospectively reviewed 1372 patients with intracranial meningioma who were surgically treated between September 1986 and July 2018. From this cohort, 21 patients with IVM were identified. The clinical, radiologic, surgical, and follow-up records were analyzed. The archival pathologic specimens were reviewed. Tissue microarray blocks were performed from the formalin-fixed, paraffinembedded samples of all IVM cases, 2 choroid plexus tissue adjacent to the tumors, and 10 extraventricular fibrous meningioma cases selected as control randomly. Immunohistochemical staining with the antibodies S-100, SOX10, NGFR, and OTX2 was performed according to the protocols indicated by the manufacturers.-RESULTS: Surgical complications included hemiparesis in 1 patient (5%), postoperative seizure in 1 patient (5%), sensorial aphasia in 1 patient (5%), and preexisting headache in 1 patient (5%). Seventeen (81%) of the IVMs had grade I pathology and 4 (19%) had grade II pathology. The immunoprofile of IVMs is identical to the immunoprofile of normal choroid plexus epithelium.-CONCLUSIONS: Transcortical approaches using intraoperative ultrasonography and intraoperative monitoring with avoidance of eloquent cortical areas can achieve good outcomes. Resection of the choroidal attachments should be attempted. Our results indicate that IVMs do not show arachnoid cap cell phenotype and the findings support that IVMs originate from the choroid plexus epithelium or the progenitors of the choroid plexus epithelium.

An unusual growth of an intraventricular meningioma: a case report

Neurological Sciences, 2011

Intraventricular meningiomas are rare often histologically benign tumors arising most always from the trigonal region of the lateral ventricle. We report the first described case of a rapidly growing histologically benign intraventricular meningioma in a 68-year-old woman whose magnetic resonance imaging (MRI) executed 1 year before surgical operation was negative for intracranial mass lesion.

MR and MRS Characteristics of Intraventricular Meningioma

Journal of Neuroimaging, 2009

Meningiomas are frequent intracranial, non-glial tumors of adults. We present the unusual left lateral ventricular localization of meningioma in a 51-year-old man. The magnetic resonance (MR) images showed well demarcated, large mass of the atrium of the left lateral ventricle with transependymal extension into the left temporal lobe. MR spectroscopy revealed the presence of "choline only" spectrum, typical for extra axial neoplasms. The mass was completely resected. The diagnosis of transitional type intraventricular meningioma, with psammoma bodies, histologic grade I was made. Progesterone and estrogen receptors were negative.

A Rare Case of a Large Intraventricular Meningioma: A Case Report

2021

Intraventricularmeningiomasare rare intracranial tumors account for 0.5-2% of all meningiomas. Most intraventricularmeningiomas present between the 3 and 6 decades with a recognized female predilection. We described here a case of large intraventricular meningioma with mass effectwho was treated successfully in our institute. A 41 year male patient having headache, blurring of vision and convulsions was diagnosed as a case of right ventricular space occupying lesion (SOL). He underwent right temperopariatal craniotomy with excision of right lateral ventricular SOL in our institute. On histopathology, it was found meningioma grade 1. Patient had tremendous clinical improvement postoperatively. We can conclude from this case that large intraventricularmeningiomas if treated properly these patients can have better outcome

Multiple High Grade Rhabdoid Papillary Meningiomas Mimicking Choroid Plexus Carcinoma: A Case Report

Iranian Journal of Pathology, 2019

Rhabdoid papillary meningioma is an uncommon aggressive variant of meningioma which has the potential to metastasize and spread throughout the brain and even out of the cranium. Herein, we present recurrence of the brain tumor in a 26-year-old woman. The patient had history of the surgery for two lesions in the right temporal lobe and the left cerebellopontine angle. Imaging showed three lesions in the right temporal lobe, the right occipital horn wall, and the left cerebellopontine angle. These radiologic findings were mostly suggestive of atypical meningioma. In the surgical view, the mass was solid-cystic reddish Cauliflower-shaped in the right temporal lobe attaching to the temporal horn. The microscopic examination showed a cellular neoplasm with the sheet-like and papillary growth pattern. Individual cells had vesicular nuclei some with prominent nucleoli and eosinophilic cytoplasm. The areas of the tumor cells showed round eccentric nuclei and prominent nucleoli with eosinophilic cytoplasm. Immunohistochemistry studies showed diffuse positivity of tumor cells with Vimentin, EMA, and S100. The overall clinical, radiological and histopathological examinations were compatible with high grade rhabdoid-papillary meningiomas. In the present case study, we discuss imaging and histomorphological features of this rare entity of meningiomas.

Meningiomas of the lateral ventricles: A review of 10 cases

Neurocirugía, 2008

Background. Intraventricular meningiomas are rare tumours that represent about 2% of all intracranial meningiomas, and represent one of the most challenging problems in neurosurgery. They are located deep within the brain and often are sizable and highly vascular. We report on a series of 10 meningiomas of the lateral ventricles treated at our institution during the last 28 years. Patients. Ten patients (6 women, 4 men; mean age 41.6 yrs) were admitted to our medical center between 1978-2005 with meningioma of the lateral ventricles. Headache was the first symptom in 8 cases and ocular signs were present in 5 patients. Results. Seven tumours were located in the right ventricle (70%) ranging in size from 2-8 cm, with 7 tumours larger than 3 cm in diameter. Nine patients underwent surgery with total excision in 8 cases and subtotal in the other; the remaining patient only received radiosurgery. Conclusions. Total resection is the gold standard for treatment which was possible in all but one of the cases undergoing surgery. KEY WORDS: Brain tumours. Intraventricular meningiomas. Lateral ventricle.

Intraventricular cystic meningioma

Journal of Cancer Research and Therapeutics, 2010

We report a case of a 45-year-old male patient with intraventricular cystic meningioma located in the left lateral ventricle. He presented with complaints of global headache, progressively increasing loss of memory, and frequent episodes of abnormal behavior, of 1 month duration. At the time of hospital admission, his general and neurological examination was normal. Neuroimaging studies showed a left lateral ventricular enhancing mass, composed of mixed solid and cystic areas. The tumor was completely excised via the anterior transcallosal approach. A histological examination revealed a meningothelial meningioma without any atypia. The aim of this report is to present the occurrence of an intraventricular cystic meningioma.

Lymphoplasmacyte-Rich Meningioma of the Third Ventricle: Case Report

Arquivos Brasileiros de Neurocirurgia: Brazilian Neurosurgery

Introduction Meningiomas are the most common primary intracranial tumors, accounting for up to 35% of the neoplasms in this category. Approximately 10–20% of these neoplasms are histologically atypical, and the lymphoplasmacyte-rich meningioma (LPM) corresponds to a very rare subtype of meningioma that is characterized histopathologically by massive infiltrates of inflammatory cells. The case described in the present study is the sixth case of an intraventricular LPM found in the literature and the first case considering the location in the third ventricle. Case Description A 21-year-old male without previous comorbidities sought medical attention due to visual impairment (complaining of intermittent visual blur) for 2 months. A magnetic resonance imaging of the brain confirmed the presence of a well-delimited solid mass in the third ventricle of 3.0 × 2.3 cm with a cystic component that extended itself inferiorly and distorted the visual pathway anatomy. Neurosurgeons decided to ac...

Paediatric intraventricular meningiomas. A report of two cases

The Australasian medical journal, 2012

Meningiomas are rare in children comprising less than 3% of paediatric brain tumours and only 1.5-1.8% of all intracranial neoplasms. Intraventricular meningiomas (IVM) account for 0.5-5% of all meningiomas. They arise in the ventricles from arachnoid cap cells contained within the choroid plexus, the tela choroidea, or the velum interpositum. Paediatric tumours also show an association with neurofibromatosis type 2 and previous radiation exposure.We present two cases of intraventricular meningiomas, both in children. The age and site of the lesion in the two cases are uncommon. Excision of the lesions caused a total subsidence of the symptoms with no reported recurrences.
