Meningioma in Fourth Ventricle of Brain: A Case Report and Literature Review (original) (raw)

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.

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

Meningioma of the anterior part of the third ventricle

Acta Neurochirurgica, 1981

The authors report the clinical features, radiological findings, and surgical management in a case of meningioma of the anterior part of the third ventricle in a 5%year-old woman. The unusual fact in our patient compared with the other reported cases is that she never developed symptoms or signs of increased intracranial pressure. A review of the literature is presented. Ours is the second case in which CT scan has been used in the diagnosis.

Primary Extracranial Meningiomas: An Analysis of 146 Cases

Head and Neck Pathology, 2009

Primary extracranial meningiomas are rare neoplasms, frequently misdiagnosed, resulting in inappropriate clinical management. To date, a large clinicopathologic study has not been reported. One hundred and forty-six cases diagnosed between 1970 and 1999 were retrieved from the files of the Armed Forces Institute of Pathology. Histologic features were reviewed, immunohistochemistry analysis was performed (n = 85), and patient follow-up was obtained (n = 110). The patients included 74 (50.7%) females and 72 (49.3%) males. Tumors of the skin were much more common in males than females (1.7:1). There was an overall mean age at presentation of 42.4 years, with a range of 0.3-88 years. The overall mean age at presentation was significantly younger for skin primaries (36.2 years) than for ear (50.1 years) and nasal cavity (47.1 years) primaries. Symptoms were in general non-specific and reflected the anatomic site of involvement, affecting the following areas in order of frequency: scalp skin (40.4%), ear and temporal bone (26%), and sinonasal tract (24%). The tumors ranged in size from 0.5 up to 8 cm, with a mean size of 2.3 cm. Histologically, the majority of tumors were meningothelial (77.4%), followed by atypical (7.5%), psammomatous (4.1%) and anaplastic (2.7%). Psammoma bodies were present in 45 tumors (30.8%), and bone invasion in 31 (21.2%) of tumors. The vast majority were WHO Grade I tumors (87.7%), followed by Grade II (9.6%) and Grade III (2.7%) tumors. Immunohistochemically, the tumor cells labeled for EMA (76%; 61/80), S-100 protein (19%; 15/78), CK 7 (22%; 12/55), and while there was ki-67 labeling in 27% (21/78), \3% of cells were positive. The differential diagnosis included a number of mesenchymal and epithelial tumors (paraganglioma, schwannoma, carcinoma, melanoma, neuroendocrine adenoma of the middle ear), depending on the anatomic site of involvement. Treatment and follow-up was available in 110 patients: Biopsy, local excision, or wide excision was employed. Follow-up time ranged from 1 month to 32 years, with an average of 14.5 years. Recurrences were noted in 26 (23.6%) patients, who were further managed by additional surgery. At last follow-up, recurrent disease was persistent in 15 patients (mean, 7.7 years): 13 patients were dead (died with disease) and two were alive; the remaining patients were disease free (alive 60, mean 19.0 years, dead 35, mean 9.6 years). There is no statistically significant difference in 5-year survival rates by site: ear and temporal bone: 83.3%; nasal cavity: 81.8%; scalp skin: 78.5%; other sites: 65.5% (P = 0.155). Meningiomas can present in a wide variety of sites, especially within the head and neck region. They behave as slow-growing neoplasms with a good prognosis, with longest survival associated with younger age, and complete resection. Awareness of this diagnosis in an unexpected location will help to avoid potential difficulties associated with the diagnosis and management of these tumors.

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.
