Giant intracranial aneurysms presenting with massive cerebral edema

|October 1, 1984
Summary
Giant middle cerebral artery aneurysms with thrombosis caused severe brain swelling and poor outcomes in two patients. Surgical resection led to disastrous results, highlighting the risks of such interventions.
Area of Science:
- Neurosurgery
- Vascular Neurology
- Neuroradiology
Background:
- Giant aneurysms of the middle cerebral artery (MCA) are rare cerebrovascular lesions.
- These aneurysms can present with neurological deficits due to mass effect or complications like thrombosis.
Observation:
- Two cases of giant MCA aneurysms presented with acute hemiparesis and aphasia.
- Computed tomography (CT) scans revealed intraaneurysmal thrombosis and significant cerebral edema without recent hemorrhage.
Findings:
- Surgical resection of the aneurysms was performed in both patients.
- Despite surgical intervention, both patients experienced disastrous outcomes, suggesting high morbidity associated with these cases.
Implications:
- The findings suggest that intraaneurysmal thrombosis in giant MCA aneurysms may trigger severe, rapid brain swelling.
- Understanding the mechanisms of brain swelling is crucial for managing these complex vascular lesions.
- The disastrous outcomes underscore the need for careful consideration of treatment strategies and potential risks in managing giant MCA aneurysms with thrombosis.
