1. Review the spectrum of vasoconstrictive diseases which fall under the umbrella of Reversible Cerebral Vasoconstriction Syndrome (RCVS) with a discussion of the most common etiologies, the currently understood pathophysiology and the potential complications with a particular focus on Posterior Reversible Encephalopathy Syndrome (PRES). 2. Pictorial case review of RCVS from our collection and a review from the literature. 3. Review of the complications associated with RCVS, including PRES, hemorrhage, and infarction. 4. Recognizing the radiographic appearance and complications of RCVS on anatomic imaging can suggest underlying vascular pathology and lead to angiographic imaging necessary for the diagnosis of RCVS. 5. One explanation for the general etiology of RCVS is failure of the central nervous system vascular autoregulatory system, which may explain its frequent co-existence with PRES.
