Abstract
BACKGROUND
Nontraumatic convexal subarachnoid hemorrhage (cSAH) is a rare type of atypical subarachnoid hemorrhage. It mainly presents as a focal and transient neurological deficit with similar manifestations as transient ischemic attack.
CASE SUMMARY
We report a case of a 64-year-old man who visited the hospital with paroxysmal left-sided numbness and weakness is presented in this study. Computed tomography examination indicated a high-density image of the right frontal-parietal sulcus. Digital subtraction angiography showed severe stenosis at the right anterior cerebral artery A2-A3 junction (stenosis rate approximately 70%).
CONCLUSION
The findings of this case indicate that anterior cerebral artery stenosis may lead to the occurrence of cSAH.
Core Tip: This is a rare case of convexal subarachnoid hemorrhage (cSAH) with transient ischemic attack as the first presentation. We reported the whole course. This case indicated the clinical characteristics, laboratory findings, imaging examinations and adjustment of treatment and discussed the possible relation between anterior cerebral artery stenosis and the occurrence of cSAH.
