The purposes of this exhibit are: 1. Review the various clinical presentations that encompass the broad diagnostic spectrum of reversible cerebral vasoconstriction syndrome (RCVS). 2. Present CT, MRI, and angiographic imaging findings of various clinical entities that are categorized as variants of RCVS. Image findings will be discussed and examples will be provided in a case-based format. Examples of post-therapeutic imaging will also be presented. 3. Discuss controversies in the diagnosis and management of RCVS. 4. Discuss potential complications of intra-arterial therapy in RCVS.

Conditions categorized under spectrum of reversible cerebral vasoconstriction syndrome (RCVS) - Spontaneous (Call-Fleming, benign angiopathy of the CNS, thunderclap headache with reversible vasospasm) - Related to use of vasoactive drugs - Post-partum angiopathy - Migrainous vasospasm - Other associations - Associations with PRES Complications of RCVS Imaging features - CT - MRI/MRA - Angiography Diagnosis Management Complications of treatment
