Abstract：Convexal subarachnoid hemorrhage (cSAH) is characterized by simple subarachnoid hemorrhage.The etiology and clinical manifestations of cSAH are varied,and transient cerebral ischemia is rare.In addition,the most cases of cSAH reported stenosis or occlusion of responsible vessels in the anterior circulation,while the presence of responsible vessels in the posterior circulation of cSAH was rare.The case mentioned in this study was cSAH presented by transient cerebral ischemia,and the patient was basilar artery stenosis or occlusion with left parietal cSAH.The patient was clinically stable after treatment with stable plaque.This case suggests that narrowing or occlusion of the basilar artery may cause cSAH formation.Although the etiology of this disease has not been determined,the patient did not have an adverse prognosis.
