Meningiomas of the lateral ventricles: A review of 10 cases (original) (raw)

Meningiomas of the lateral ventricles

Journal of Neurosurgery, 1981

✓ The clinical and neuroradiological findings and the surgical results in a series of 18 patients with meningiomas of the lateral ventricles, operated on over a 23-year period, are described. This experience is compared with previously reported series and the following conclusions are drawn: 1) these tumors have no characteristic symptomatology; 2) the preoperative diagnosis should be reached by means of both computerized tomography and carotid and vertebral angiography; 3) the safest surgical approach is through a sagittal paramedian parieto-occipital cortical incision; and 4) piecemeal removal is crucial for achieving total extirpation of the tumor with minimum damage of the surrounding brain tissue and for careful intraoperative hemostasis.

Meningiomas of the lateral ventricles of the brain in children

Child's Nervous System, 1998

A 12-year-old girl was admitted (in November 1994) with a 2-year history of headache (worsening over the last 2 months) and nausea and vomiting of 2 weeks' duration. Neurological examination revealed a slight left-sided hemiparesis and bilateral papilloedema Child's Nerv Syst (1998) 14: 350-353 Abstract Meningiomas of the lateral ventricles of the brain are rare tumours, accounting for approximately 0.5-5% of all intracranial meningiomas. Their natural history and symptomatology and the possibilities of early diagnosis are presented. The intraventricular location of the slow-growing benign mass provides a compensatory mechanism in the form of reserve space, which contributes to the delay in clinical demonstration of symptoms and signs. This makes the choice of diagnostic procedure an essential prob-lem. CT and MRI are useful in detecting these masses, and magnetic resonance angiography (MRA) has also proved to be of great value in demonstrating the vascular supply of the tumour. This paper deals with two cases. In case 1 CT, MRI and MRA and in case 2 CT examination proved to be very useful. The tumours were removed by a transcortical approach in the posterior area.

Intraventricular Meningiomas -Case Series and Review of Literature

Introduction: Meningioma is the most common benign primary intracranial tumour after glioma. Meningioma occuring in intraventricular region is very rare. When located in intraventricular space, majority of intravemtricular meningioma (IVM) are located in lateral ventricles. Material and methods: This is a Study of four cases of intraventricular meningioma in Madras medical College from January 2022 to December 2022. In this study, the symptoms, MRI findings, operative procedure, histology images, surgical outcomes and a detailed review is done from various literature. Results: Among the various symptoms, headache, disturbance in vision, changes in cognition and speech disturbance were commonly found. The site of all the lesion was in the lateral ventricle. MRI was used to confirm the diagnosis before surgery. In our patients, the intraventricular meningioma was completely excised via parietal craniotomy or temporoparietal craniotomy based on the location of the tumour. The tumour was completely excised in all four patients. Histologically it was meningothelial meningioma in all 4 patients. Conclusion: From our case series we observed that all the IVM were WHO grade I and total excision is possible in intraventricular meningiomas with properly planned surgical trajectory with minimum post operative morbidity.

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

Intraventricular meningiomas: a consecutive series of 22 patients and literature review

Neurosurgical Review, 2013

Intraventricular meningiomas (IVMs) are rare tumors of which the majority is located in the lateral ventricles. Most published series on the subject includes only a few patients. We analyzed our series of IVMs with a special interest in clinical features, outcome, and complications related to surgery. Twenty-two patients underwent resection of IVMs from 1990 to 2010 at Oslo University Hospital. Surgical and medical records were retrospectively analyzed. The IVMs were located in the trigonum of the lateral ventricles (20/22), in the third ventricle (1/22), and in the fourth ventricle (1/22). The most common symptoms and signs were headache, vertigo, nausea/vomiting, mental disturbances, balance impairment, and corticospinal tract signs. Visual field deficit was present preoperatively in two patients. Tumors of the lateral ventricles were resected via a transcortical parieto-occipital approach; the tumors in the third and fourth ventricle via a frontal transcortical and suboccipital route, respectively. Complete tumor resection was achieved in all but one case. Histology was WHO grade I in 20/22 and grade II in 2/22. Surgical mortality was 0 %.

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.

Meningioma in Fourth Ventricle of Brain: A Case Report and Literature Review

Asian journal of neurosurgery

Meningiomas are benign tumors origin from central nervous system. They usually involve cephalic, paravertebral soft tissues, skin and in rare cases in the ear, temporal bone, mandible, foot, lung, and mediastinum. In this case, we report an unusual case of meningioma which placed in the fourth ventricle. A 14-year-old man with seizure and headache referred to our ward. The magnetic resonance imaging reported bilateral acoustic neuroma and fourth ventricle meningioma. The patient was scheduled for total tumor resection and the histopathology revealed psammomatous type of meningioma. The patient discharged with good general status.

Rare Case of Young Patient with Intraventricular Angiomatous Meningioma

Global Journal of Medical Research, 2021

Pediatric meningiomas are rare and account for only 2.2% of CNS tumors. In this age group, they are more frequently located in atypical sites, such as, mainly, the ventricular system, with a frequency of 8.8 to 13.6%. Adding this to the fact that the angiomatous subtype constitutes only 2.1% of all meningiomas, the rarity of the case reported here i s corroborated. We report a 17-year-old female patient diagnosed with intraventricular angiomatous meningioma; she underwent surgical resection of the tumor in the body and frontal horn of the right lateral ventricle, and there was no neurological sequela. With a follow-up of 4 years, there was no recurrence and the patient had clinical stability. Intraventricular tumors usually have slow growth and reach considerable size until they cause symptoms and then are diagnosed. In addition, the tumor’s deep location and proximity to eloquent areas make such tumors an neurosurgical challenge. The angiomatous subtype, due to the presence of hype...
