Background Posterior reversible encephalopathy syndrome (PRES) is a neurological complication caused by cerebral hyperperfusion.Case Report A 46-year-old male presented with decreased mental status, left facial palsy, and left-sided weakness after video-assisted thoracoscopic surgery for a solitary pulmonary nodule.During Lead Wires the surgery, phenylephrine was infused intravenously for general anesthesia-induced hypotension.
High signal intensity at the right parietooccipital lobe was noted on fluid-attenuated inversion recovering imaging and diffusion-weighted imaging.His neurological symptoms improved two days after initial presentation.Follow-up diffusion-weighted imaging showed resolution of the brain lesions 10 days after the surgery.
Conclusions We report a patient who presented with PRES after administration of phenylephrine Vitamin B Complex during resection of a solitary pulmonary nodule.PRES should be considered for patients presented with acute neurologic symptoms following surgical procedures.
