Info

Nomenclature: 1960s – 2000s • Call or Call-Fleming syndrome • Postpartum angiopathy • Eclampsia associated vasoconstriction • Migraine ‘angiitis’ • Thunderclap HA with reversible ‘vasospasm’ • Drug induced ‘angiitis’ • CNS ‘pseudovasculitis’ • Benign angiopathy of the CNS (BACNS) ‘<strong>RCVS</strong>’ includes all of the above
Key Elements for Diagnosis 1. Severe, acute, recurrent ‘thunderclap’ headache with or without additional neurologic signs or symptoms 2. DSA / CTA/ MRA : multifocal vasoconstriction 3. No evidence for aneurysmal SAH 4. Normal CSF (protein
