“…Most cases are reported in isolated case reports or case series describing all types of intraventricular meningiomas. [1,4,5,7,9,14,16-18,23] TVM most commonly not only presents with symptoms of HCP but can also present with ataxia, hemiparesis, and hypothalamic dysfunction. Our patient presented with acute IVH and obstructive HCP.…”

Background: Third ventricular meningiomas are exceedingly rare intracranial tumors that may present with intraventricular hemorrhage. Case Description: The patient is 46-year-old who initially presented with obstructive hydrocephalus from a presumed vascular lesion and who was treated with endoscopic third ventriculostomy. He presented 3 years later with acute intraventricular hemorrhage and hydrocephalus. The hemorrhage was evacuated and the third ventricular tumor was resected, and the patient made an excellent recovery. Histopathological analysis identified the tumor as the World Health Organization Grade II meningioma. Conclusion: Third ventricular meningioma is a rare tumor that may present with hemorrhage and obstructive hydrocephalus. Surgical resection can be helpful for this rare presentation of intracranial meningioma.

“…[ 27 ] Since the adjacent cells of the neural crest contribute to the formation of leptomeninges, some of these cells might migrate together with the choroid plexus, explaining the presence of arachnoid cells reported in normal choroid plexus stroma. [ 27 30 ] Intraventricular meningiomas are thought to arise from these arachnoid cells in the choroid plexus. [ 11 30 ] Similarly in the VI, the close vicinity of the choroid plexus in regard to the inferior leaflet could bring a significantly larger “pool” of arachnoid cells in the region that could potentially give rise to meningiomas.…”

Background:Meningiomas of the velum interpositum in the roof of the third ventricle are rare. Knowing from which leaflet the meningioma originates and thus its relationships with the internal cerebral and Galen veins, may help in choosing the surgical approach.Case Description:We report the case of a 40-year-old male with a meningioma arising from the superior leaflet of the velum interpositum. The tumor was resected successfully using the infratentorial-supracerebellar approach. Reviewing the literature, of the 22 reported cases of velum interpositum meningiomas, sufficient information regarding the precise location of the origin of the tumor was provided in 14 cases, all of which were from the inferior leaflet.Conclusion:We report the first case of velum interpositum meningioma arising from the superior leaflet and give a potential explanation as to why meningiomas of the velum interpositum occur more commonly on the inferior leaflet. Distinguishing from which of the two leaflets the tumor originates may influence the surgical strategy.

Third ventricular atypical meningioma which recurred with further malignant progression

Meningiomas in the third ventricle are rare, with only very few cases reported in the literature. We report a case of primary third ventricular anaplastic meningioma in a 49-year-old man who presented with progressive weakness of the left limbs and headache. Magnetic resonance imaging revealed a tumor which seemed to arise from the right thalamus and extending into third ventricle. The tumor was heterogeneously enhanced with gadolinium. It was totally removed by right transventricular-subchoroidal approach. The lesion was intraoperatively found to be whitish hard and embedded in right thalamus, but had attachment to choroid plexus near foramen Monroi with narrow interface. The histological diagnosis was atypical meningioma, WHO Grade II. Lesion recurred 20 months later and was resected via the same approach, which turned out to be papillary meningioma, WHO Grade III. The patient had second recurrence 23 months after second surgery which was operated and the final diagnosis was anaplastic meningioma (WHO Grade III). Literature review showed meningioma of the third ventricle is quite exceptional and more than half of the cases were aggressive subtypes (Grade II or III).
