Abstract:
We report a case of a patient with olfactory groove meningioma associated with multiple aneurysms. The association between intracranial aneurysms and meningiomas is infrequent and perhaps it is due to chance alone; many theories have been formulated to explain it. In the cases with both lesions, meningiomas are more frequently located at level of the convexity while aneurysms are more often located at level of the anterior cerebral-anterior communicating artery complex or at level of the middle cerebral artery.
Insights
This case study highlights a rare occurrence of olfactory groove meningioma alongside multiple intracranial aneurysms. The study discusses the infrequent association between these two conditions and their typical locations.
Area of Science:
- Neurosurgery
- Neurology
- Oncology
Background:
- Meningiomas are tumors arising from the meninges, the membranes surrounding the brain and spinal cord.
- Intracranial aneurysms are abnormal bulges or ballooning in the wall of a blood vessel in the brain.
Observation:
- The case involves a patient diagnosed with an olfactory groove meningioma.
- The patient also presented with multiple intracranial aneurysms.
Findings:
- The co-occurrence of meningiomas and intracranial aneurysms is infrequent.
- When both conditions are present, meningiomas are often found on the brain's convexity.
- Aneurysms are more commonly observed in the anterior cerebral-anterior communicating artery complex or middle cerebral artery regions.
Implications:
- This case contributes to understanding the rare association between meningiomas and aneurysms.
- Further research may elucidate potential shared etiological factors or coincidental occurrences.
- Understanding lesion locations is crucial for surgical planning and patient management.
