“…Total removal of third ventricle meningiomas can be achieved through the interhemispheric transcallosal, interhemispheric trans-lamina terminalis, or transcortical-transventricular approaches. [1][2][3]11,13,15,17,18) The transcorticaltransventricular approach requires cortical incision to reach the lateral ventricle. This approach is best used for lesions with a significant intraventricular component within the third ventricle and associated enlarged lateral ventricles.…”

A 63-year-old man presented with headache. Magnetic resonance imaging showed a mass lesion homogeneously enhanced with gadolinium, which occluded the route from the third ventricle to the aqueduct. The patient underwent surgery for removal of the tumor via the right frontal transcorticaltransventricular approach to the third ventricle via the transchoroidal route. Intraoperative diagnosis was meningioma. Total removal of the tumor was achieved in piecemeal fashion (Simpson grade 1). The histological diagnosis was meningothelial meningioma. The patient was discharged without neurological deficits. Third ventricle is a rare and difficult site to remove tumor totally. However, total removal was needed in this case of benign meningioma, so the operative strategy and the differential diagnosis before operation is considered to be very important.

“…Third ventricle meningiomas arise from the stroma of the choroid plexus or from the tela choroidea which together constitute the membrana tectoria 3,8,14,17,18 . The presence of arachnoid cell nests in the normal choroid plexus stroma has been illustrated in the literature and a thorough examination of the choroid plexus usually reveals small or sometimes larger collections of these cells 4 .…”

SummaryThird ventricle meningiomas are rare, representing approximately 0,15% of all meningiomas. The majority of third ventricular meningiomas are located posteriorly in the pineal region. Less commonly, they arise in the anterior part of the third ventricle. We report the cases of two patients with large and giant meningiomas originating in the anterior part of the third ventricle. KEY WORDS: Meningioma. Intraventricular tumor. Third ventricle Meningiomas del tercer ventrículo. Presentación de dos casos ResumenLos meningiomas del tercer ventrículo son raros. Representan, aproximadamente, el 0,15% de todos los meningiomas. La mayoría de los meningiomas del tercer ventrículo se localizan en la parte posterior, en la región pineal. Menos frecuentemente se originan en la parte anterior del tercer ventrículo. Presentamos los casos de dos pacientes con meningiomas grandes y gigantes, con origen en la parte anterior del tercer ventrículo.PALABRAS CLAVE: Meningioma. Tumor intraventricular. Tercer ventrículo.Meningiomas comprise 13-18% of all intracranial tumors; intraventricular meningiomas constitute 0,5-5,0% of all meningiomas 8,19,21,22 . The majority of intraventricular meningiomas are found in the trigone of the lateral ventricle, predominantly on the left side 4 . Those meningiomas arising in the third ventricle are rare, approximately 0,15% of all meningiomas 3,6,18 , and are usually located posteriorly in the pineal region 6,14,17 . Less commonly, third ventricle meningiomas arise in the anterior part of the third ventricle 6,15 . We report two cases with large and giant meningiomas originating in the anterior part of the third ventricle and discuss the differential diagnosis and treatment options of this rare tumor. Case 1A 25-year-old woman was admitted with a three month history of headache and almost three weeks of left sided weaknes. Neurological examination disclosed papilledema, 4/5 left hemiparesis, and left hemihypesthesia. Magnetic resonance (MR) imaging of the brain demonstrated an homogeneously enhancing midline mass within the third ventricle causing hydrocephalus (Figure 1 a,b). The tumor, which was adherent to the anterior portion of the third ventricle, was removed near totally via an interhemispheric transcallosal approach (Figure 2 a,b). Postoperative course was uneventful. Pathological examination revealed a psammomatous meningioma. Case 2A 25-year-old woman was admitted with a four month history of headache and diplopia on right lateral gaze, and one week of vomiting. Neurological examination disclosed only papilledema. MR imaging of the brain demonstrated an homogeneously enhancing third ventricular mass (Figure 3 a,b). A right sided transcortical transventricular approach to the third ventricle was performed. The tumor was near totally removed (Figure 4 a,b). Postoperative course was uneventful. Pathological examination revealed a meningothelial meningioma.

Intraventricular meninigiomas: a report of 25 cases

In order to study the clinical characteristics of intraventricular meningiomas, we analyzed retrospectively 25 patients and reviewed the literature with regard to incidence, clinical manifestation, imaging features, preoperative diagnosis, surgical findings, and histopathological results. Intraventricular meningiomas are quite rare, but they represent an important differential diagnosis of intraventricular neoplasms. Computed tomography or magnetic resonance imaging enable a correct diagnosis of intraventricular meningiomas in most of the cases. The tumors often grow slowly to a substantial size before they become symptomatic. The operative route should be selected according to the tumor's location. Out of the 24 lateral ventricular meningiomas in our series, 20 were resected via a posterior parieto-occipital transcortical approach, two were resected via a transcallosal approach, and another two tumors, located in the frontal horn and body of the lateral ventricle, were resected via a frontal approach. A median suboccipital craniotomy was performed for the fourth ventricular meningioma. The parieto-occipital route for lateral ventricular meningiomas is a safe surgical approach, which is not necessarily associated with postoperative visual deficits. Piecemeal removal of the tumor can be safely and easily performed and special attention should be paid to the choroidal vessels intraoperatively.
