[A meningioma associated with AVM: a case report]
Abstract:
This paper reports a case of meningioma associated with AVM. A 67 years old lady showed transient rt. lower hemiparesis with severe headache, nausea and consciousness disorder. Bilateral carotid angiogram and CT scan revealed lt. convexity meningioma and AVM. Lt MCA and ACA entered into the AVM from which several draining vessels entered into the deep venous system. These two lesions were removed by one stage. It is quite rare that cerebral tumor associates with intracranial AVM. Only two cases of meningioma associated with AVM have been reported.
Insights
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.
