Potential Complications of RCVS. A Convexity subarachnoid hemorrhage. The linear hypointensity demonstrated by gradient echo imaging indicated presence of blood within the cortical sulci. B Intracerebral hemorrhage shown as hypointense lesions on susceptibility weighted imaging. C Posterior reversible encephalopathy syndrome appearing as hyperintense lesions on fluid attenuated inversion recovery imaging. D Ischemic stroke demonstrated by diffusion weighted imaging. All the lesions are indicated by yellow arrow heads. Note that A–C are earlier complications that tend to occur within the first 2 weeks of disease while D occurs later at around 2–3 weeks after onset
