We describe two cases of non-aneurysmal subarachnoid hemorrhage (SAH) and multifocal stenosis of the intracranial arteries. The patients' histories together with magnetic resonance angiography, vessel wall imaging and transcranial Doppler (TCD) indicated that the SAH was due to vasculitis or reversible cerebral vasoconstriction syndrome (RCVS). Differential diagnosis of vasculitis and RCVS is important because the treatment strategies are different: immunosuppressants in vasculitis and calcium channel blockers in RCVS. Vessel wall magnetic resonance imaging and TCD can be helpful in differentiating them.
我们描述了两例非动脉瘤性蛛网膜下腔出血（SAH）及颅内动脉多灶性狭窄的病例。患者的病史，结合磁共振血管造影、血管壁成像和经颅多普勒（TCD）检查表明，SAH是由血管炎或可逆性脑血管收缩综合征（RCVS）所致。血管炎和RCVS的鉴别诊断很重要，因为治疗策略不同：血管炎使用免疫抑制剂，RCVS使用钙通道阻滞剂。血管壁磁共振成像和TCD有助于对它们进行鉴别。
