Posterior Reversible Encephalopathy Syndrome Secondary to CSF Leak and Intracranial Hypotension: A Case Report and Literature Review

Figure 2

It represents a stepwise mechanistic explanation of pathophysiologic processes that result in vasogenic edema and PRES in context of CSF leak and intracranial hypotension. SBP: systolic blood pressure, CSF: cerebrospinal fluid, MAP: mean arterial pressure, ICP: intracranial pressure, CPP: cerebral perfusion pressure, BBB: blood brain barrier, PRES: Posterior Reversible Encephalopathy Syndrome, and MRI: magnetic resonance imaging.
