Diagnostic Value of Thunderclap Headache and Convexal Subarachnoid Hemorrhage for Reversible Cerebral Vasoconstriction Syndrome: A Case Report

Reversible cerebral vasoconstriction syndrome (RCVS) is an underdiagnosed cause of convexal subarachnoid hemorrhage, characterized by thunderclap headache associated with focal and segmental intracranial vasoconstriction. It can appear complications such as intracerebral hemorrhage, seizures, poster...

Description
Summary:Reversible cerebral vasoconstriction syndrome (RCVS) is an underdiagnosed cause of convexal subarachnoid hemorrhage, characterized by thunderclap headache associated with focal and segmental intracranial vasoconstriction. It can appear complications such as intracerebral hemorrhage, seizures, posterior reversible leukoencephalopathy, or ischemic stroke. Our objective is to present the case of a 51-year-old woman with an RCVS diagnosis, who had a normal digital subtraction angiography at the illness onset. We highlight the high diagnostic value of thunderclap headache and convexal subarachnoid hemorrhage. We also highlight the importance of repeating the angiographic studies in the second week when there is strong diagnostic suspicion.
