Summary
Middle meningeal artery (MMA) aneurysms are rare, and their presentation with epilepsy is highly unusual. This case highlights a true MMA aneurysm revealed by drug-resistant epilepsy, successfully treated with surgery.
Area of Science:
- Neurology
- Neurosurgery
- Vascular Neurology
Background:
- Aneurysms of the middle meningeal artery (MMA) are exceptionally rare, with distinct types including true aneurysms (often pathological) and pseudoaneurysms (associated with fractures).
- Epilepsy as a presenting symptom of an MMA aneurysm has not been previously documented.
Observation:
- A 57-year-old patient with hypertension developed drug-resistant epilepsy originating from the right temporal area.
- Cerebral angiography identified an isolated right middle meningeal artery aneurysm without other intracranial abnormalities.
- The aneurysm was intradural, adjacent to the temporal cortex, and surgically treated via coagulation.
Findings:
- This case presents a rare instance of a true middle meningeal artery aneurysm manifesting solely as epilepsy.
- Surgical intervention involving aneurysm coagulation led to favorable outcomes with improved seizure control.
Implications:
- The unusual presentation of MMA aneurysms with seizures underscores the need for comprehensive diagnostic evaluation in refractory epilepsy cases.
- Management strategies for isolated MMA aneurysms are comparable to those for other intracranial aneurysms, with surgical coagulation demonstrating efficacy.
