Within a short period, she experienced blurred vision, generalized tonic-clonic seizures, and progressive confusion. On arrival at the emergency department, her blood pressure exceeded 220/120 mmHg. The emergency physician immediately considered several neurological emergencies, including acute ischemic stroke, intracranial hemorrhage, cerebral venous thrombosis, encephalitis, and hypertensive encephalopathy. A non-contrast brain CT was rapidly performed. Although no intracranial hemorrhage was identified, subtle bilateral hypodense lesions were noted within the parieto-occipital white matter. These findings prompted immediate MRI evaluation. Magnetic Resonance Imaging demonstrated symmetric vasogenic edema involving both parieto-occipital lobes. Diffusion-weighted imaging revealed no evidence of restricted dif...
