An unexpected turn: Posterior reversible encephalopathy syndrome following microsurgical resection of a brain arteriovenous malformation

This case underscores the critical importance of early neuroimaging in evaluating unexpected postoperative neurological symptoms. Recognizing central PRES and its atypical radiographic patterns enables timely diagnosis and appropriate management, avoiding unnecessary interventions. The pathophysiology likely involves postoperative endothelial dysfunction and disrupted autoregulation. This report underscores the importance of considering PRES in postoperative neurological complications and calls for further research into its mechanisms and optimal management.
