Meningiomas of the lateral ventricles of the brain
1Department of Neurosurgery, Medical University of Gdańsk.
Abstract:
Meningiomas of the lateral ventricles of the brain are rare tumours with an approximate incidence of 0.5-4.5% among all intracranial meningiomas. Four cases of intraventricular meningioma arising from the trigone are presented. In 1-st case the calcified mass was visible on straight radiographs. In 2-nd and 3-rd cases CT and angiography was performed. In 4-th case MRI and MRA proved to be very useful. The tumours were removed by transcortical approach in the posterior parietal area. The available literature on intraventricular meningiomas has been discussed.
Insights
Intraventricular meningiomas are rare brain tumors. This study presents four cases of trigone meningiomas, discussing diagnostic imaging and surgical approaches for these challenging lesions.
Area of Science:
- Neurosurgery
- Neuroradiology
- Neuropathology
Background:
- Meningiomas of the lateral ventricles are uncommon, representing 0.5-4.5% of all intracranial meningiomas.
- Intraventricular meningiomas, particularly those arising from the trigone, present unique diagnostic and surgical challenges.
Observation:
- Four cases of intraventricular meningioma originating from the trigone are detailed.
- Diagnostic imaging modalities included plain radiographs, computed tomography (CT), angiography, magnetic resonance imaging (MRI), and magnetic resonance angiography (MRA).
- A transcortical approach in the posterior parietal region was utilized for tumor resection.
Findings:
- Plain radiographs identified a calcified mass in one case.
- CT and angiography were employed in two cases.
- MRI and MRA proved highly beneficial for diagnosis in the fourth case.
Implications:
- This case series highlights the utility of advanced imaging techniques like MRI and MRA in diagnosing intraventricular meningiomas.
- The transcortical approach is a viable surgical option for trigone meningiomas.
- Further discussion of the literature provides context for these rare tumors.
