van Beers and colleagues described a 49-year-old woman admitted to hospital for thunderclap headache, blurred vision and hypertension. Based on clinical manifestations, diagnostic work-up and follow-up, the authors diagnosed the case as posterior reversible encephalopathy syndrome (PRES) [1]. We agree that PRES should be considered in this case, while differential diagnosis such as subarachnoid hemorrhage (SAH) requires further investigation and exclusion.
