BrainWaves: A Neurology Podcast


Aug 25, 2016

Posterior reversible encephalopathy syndrome: Not always posterior, or reversible, or with associated encephalopathy. These and other clinical and neuroimaging factoids are reviewed in this week's edition of BrainWaves where we discuss the various--and often disparate--features of PRES. BrainWaves podcasts and online content are intended for medical education only and should not be used to guide medical decision making in routine clinical practice. Any cases discussed in this episode are fictional and do not contain any patient health identifying information. The content in this episode was vetted and approved by Amy Pruitt. REFERENCES 1.
