Hemorragia subaracnoidea y ataque cerebrovascular hemorrágico secundario a síndrome de vasoconstricción cerebral reversible: reporte de caso

Reversible cerebral vasoconstriction syndrome (RCVS) is a frequent cause of thunderclap headache. Clinical diagnosis and neuroimages are easy and may avoid unnecessary tests and deleterious treatment. We present the case of a 72-year-old woman with recurrent thunderclap headache complicated with convexity subarachnoid hemorrhage and focal intracerebral hemorrhage that required surgical treatment. Over-the-counter nasal decongestants were believed to be the triggering factor. Neuroimages helped to diagnose and confirm the condition three months after de onset of the RCVS. Recurrent thunderclap headaches with subarachnoid hemorrhage, ischemic stroke of unknown etiology or focal intracerebral hemorrhage must guide the diagnosis to RCVS.
