Spontaneous Intracranial Hypotension associated with Posterior Reversible Encephalopathy Syndrome

Spontaneous Intracranial Hypotension (SIH) is usually due to cerebrospinal fluid (CSF) leak, resulting in loss of CSF volume. Posterior reversible encephalopathy syndrome (PRES) the inability posterior circulation brain autoregulate response significant variation blood pressure. Altered perfusion with associated blood-brain barrier disruption may lead vasogenic edema, without infarction, commonly parieto-occipital regions. Magnetic Resonance Imaging (MRI) & Spine and cerebral MR venography (MRV) are essential tools for diagnosing clinically suspected SIH PRES. We present a case PRES an 18-year-young gentleman.
