Lateral ventricular meningioma encapsulated by the dura-like membrane
Abstract:
The first case of a ventricular meningioma that was encapsulated by the dura-like membrane is reported. Magnetic resonance imaging (MRI) showed a heterogeneous mass with a low intensity rim in the trigone of the right lateral ventricle of a 63-year-old male. Histological examination revealed that the tumor was a transitional meningioma encapsulated by a thick dura-like membrane. Moreover, abundant clusters of the dura-like connective tissue existed in the tumor, indicating that both the dura-like capsule and the dura-like clusters in the tumor were created by the tumor cells.
Insights
This study reports the first case of a ventricular meningioma encapsulated by a dura-like membrane. Tumor cells appear to generate both the capsule and internal clusters of this unique dura-like tissue.
Area of Science:
- Neuro-oncology
- Neurosurgery
- Pathology
Background:
- Ventricular meningiomas are rare primary brain tumors originating from arachnoid cap cells.
- Dural encapsulation is a common feature of meningiomas, but intra-tumoral dura-like formations are unusual.
Observation:
- A 63-year-old male presented with a heterogeneous mass in the right lateral ventricle trigone.
- Magnetic resonance imaging (MRI) revealed a low-intensity rim surrounding the intraventricular tumor.
Findings:
- Histological examination confirmed a transitional meningioma with a thick dura-like capsule.
- Abundant clusters of dura-like connective tissue were identified within the tumor itself.
Implications:
- This case highlights a unique presentation of ventricular meningioma with self-generated dural structures.
- Understanding the origin of these dura-like components may offer insights into meningioma pathogenesis and behavior.
