Objective　To analyze and summarize the clinical and imaging characteristics of the patients with convexal subarachnoid hemorrhage complicated (cSAH) with acute cerebral infarction,and also to discuss the etiology,mechanisms and prognosis of this disease.Methods　Data from eight patients diagnosed as cSAH with acute cerebral infarction were analyzed.The clinical representation,imaging features,therapy and prognosis were observed.Results　Eight patients had a mean age of 58 years (range,43~68 years),and half of them were male.The main cause is large artery atherosclerosis,and this disease also can be observed in amyloid cerebrovascular disease,cardiogenic embolism,cancer radiotherapy,moyamoya disease and unknown cause.Clinical onset of the disease is characterized by conscious disturbance,headache,limb movement and sensation disorder,aphasia and limb convulsion.All patients were presented with continuous or transient limb movement and/or sensation disorder.Six cSAH cases were associated with ipsilateral acute cerebral infarction,and the other two cSAH cases with contralateral acute cerebral infarction.Six cases were presented with internal carotid artery stenosis or occlusion.All patients received timely symptomatic and etiological treatment.Antiplatelet treatments were given for three patients with large artery atherosclerosis stroke and anticoagulation therapy was initiated for patient with cardioembolic stroke.All patients had a favorable outcome (90 days modified Rankin scale score≤2),and no recurrence occurs.Conclusion　cSAH with acute cerebral infarction is characterized by various clinical manifestations and different etiologies.The most common cause is large artery atherosclerosis stenosis or occlusion.cSAH can not only occur at the same side of the infarct territory,but also at the opposite side of infarction.The patients generally can obtain good outcome after the early symptomatic and etiological treatment.
