Lipomatous meningioma associated with cerebral vascular malformation
Abstract:
A unique epileptic patient with intracranial neoplasm is reported in which a meningioma with lipomatous and osseous components was found associated with cerebral arteriovenous malformation at the same location in the right frontal lobe. The development of the leptomeningeal neoplasm may have been influenced by the underlying vascular anomaly. The cerebral arteriovenous malformation and altered hemodynamics also could have induced the sudden onset of clinical seizures, hemiparesis, and unconsciousness.
Insights
This study reports a rare case of intracranial neoplasm, specifically a meningioma with lipomatous and osseous components, alongside a cerebral arteriovenous malformation. The vascular anomaly may have influenced tumor development and triggered the patient's neurological symptoms.
Area of Science:
- Neurology
- Neurosurgery
- Pathology
Background:
- Intracranial neoplasms present diverse pathologies.
- Cerebral arteriovenous malformations (AVMs) are congenital vascular anomalies.
- The coexistence of neoplasms and AVMs is exceptionally rare.
Observation:
- A unique case of a patient with epilepsy and an intracranial neoplasm was documented.
- The neoplasm identified was a meningioma containing lipomatous and osseous elements.
- This meningioma was located in the right frontal lobe, concurrently with a cerebral arteriovenous malformation in the same area.
Findings:
- The meningioma exhibited both lipomatous and osseous differentiation.
- The cerebral arteriovenous malformation was situated precisely within the right frontal lobe.
- A potential link between the vascular anomaly and the neoplasm's development was hypothesized.
Implications:
- The findings suggest that underlying vascular anomalies like AVMs may influence the development of leptomeningeal neoplasms.
- Altered hemodynamics associated with the AVM could be a causative factor for sudden neurological deficits, including seizures, hemiparesis, and unconsciousness.
- This case highlights the complex interplay between vascular and neoplastic pathologies within the brain, offering insights into rare neurological presentations.
