Description
Summary:Posterior Reversible Encephalopathy Syndrome (PRES) is a clinical neuroradiological condition characterized by insidious onset of neurological symptoms associated with radiological findings indicating posterior leukoencephalopathy. PRES secondary to cerebrospinal fluid (CSF) leak leading to intracranial hypotension is not well recognized etiology of this condition. Herein, we report a case of PRES that occurred in the setting of CSF leak due to inadvertent dural puncture. Patient underwent suturing of the dural defect. Subsequently, his symptoms resolved and a repeated brain MRI showed resolution of brain lesions. The pathophysiology and mechanistic model for developing PRES in the setting of intracranial hypotension were discussed. We further highlighted the importance of tight blood pressure control in patients with CSF leak and suspected intracranial hypotension because they are more vulnerable to develop PRES with normal or slightly elevated bleed pressure values.
