Summary
This study details a rare case of a brain tumor (meningioma) co-occurring with an arteriovenous malformation (AVM). Both rare lesions were successfully removed simultaneously in a single surgical procedure.
Area of Science:
- Neurology
- Neurosurgery
- Neuroradiology
Background:
- Intracranial arteriovenous malformations (AVMs) are rare vascular abnormalities.
- Meningiomas are common primary brain tumors, typically benign.
- The simultaneous occurrence of meningioma and AVM is exceptionally rare in clinical practice.
Observation:
- A 67-year-old female presented with transient right lower hemiparesis, severe headache, nausea, and altered consciousness.
- Diagnostic imaging, including bilateral carotid angiography and CT scan, identified a left convexity meningioma and an associated left middle cerebral artery (MCA) and anterior cerebral artery (ACA) supplied AVM.
- The AVM exhibited drainage into the deep venous system via multiple vessels.
Findings:
- The co-existence of a meningioma and an intracranial AVM was confirmed.
- Surgical intervention involved the successful one-stage removal of both the meningioma and the AVM.
- This case adds to the minimal reported instances of meningioma associated with intracranial AVM.
Implications:
- Simultaneous surgical management of meningioma and AVM is feasible.
- Highlights the importance of comprehensive vascular and neoplastic evaluation in complex neurological cases.
- Contributes to understanding the rare association between brain tumors and vascular malformations, potentially informing future diagnostic and treatment strategies.
