Summary
Nontraumatic convexal subarachnoid hemorrhage (cSAH), a rare condition, may be caused by severe anterior cerebral artery stenosis. This case report highlights a potential link between artery stenosis and cSAH occurrence.
Area of Science:
- Neurology
- Vascular Neurology
- Neuroimaging
Background:
- Nontraumatic convexal subarachnoid hemorrhage (cSAH) is a rare condition.
- It often presents with transient neurological deficits mimicking transient ischemic attack (TIA).
Observation:
- A 64-year-old male presented with transient left-sided numbness and weakness.
- Computed tomography revealed a high-density area in the right frontal-parietal sulcus.
- Digital subtraction angiography demonstrated approximately 70% stenosis at the right anterior cerebral artery A2-A3 junction.
Findings:
- The case suggests a correlation between severe anterior cerebral artery stenosis and the development of cSAH.
- This finding offers a potential etiological explanation for certain cases of cSAH.
Implications:
- Understanding this association may improve the diagnosis and management of cSAH.
- Further research into the vascular mechanisms underlying cSAH is warranted.
- This case contributes to the literature on atypical subarachnoid hemorrhage etiologies.
