Abstract:
Middle meningeal artery aneurysms are rare. Fewer than 10 true aneurysms and 30 posttraumatic aneurysms on meningeal vessels have been reported. True meningeal aneurysms are associated with tumors, Paget's disease, arteriovenous malformations, and trauma. Potential morbidity is demonstrated with hemorrhage from true aneurysms as well as from pseudoaneurysms of the meningeal vessels. We have described a meningeal artery aneurysm of the vascular pedicle of a convexity meningioma and reviewed the literature.
Insights
Middle meningeal artery aneurysms are rare vascular conditions. This study describes a case of a meningeal artery aneurysm associated with a convexity meningioma, highlighting potential risks.
Area of Science:
- Neuroscience
- Vascular Surgery
- Radiology
Background:
- Middle meningeal artery aneurysms are exceptionally rare vascular lesions.
- Reported cases include true aneurysms and posttraumatic pseudoaneurysms.
- Associated conditions include tumors, Paget's disease, arteriovenous malformations, and trauma.
Observation:
- A case of a middle meningeal artery aneurysm originating from the vascular pedicle of a convexity meningioma is presented.
- This represents a unique association between a meningioma and a meningeal artery aneurysm.
Findings:
- The study details the specific characteristics of this rare aneurysm.
- Literature review confirms the rarity of meningeal artery aneurysms and their diverse etiologies.
- Hemorrhage from these aneurysms, both true and pseudoaneurysms, poses significant morbidity risks.
Implications:
- Accurate diagnosis and understanding of the etiology of meningeal artery aneurysms are crucial for patient management.
- The association with meningiomas warrants consideration in the differential diagnosis of vascular lesions in the head.
- Further research into the pathogenesis and optimal treatment strategies for these rare aneurysms is needed.
