Posterior reversible encephalopathy syndrome--A case report

Area of Science:

• Neurology
• Radiology

Background:

• Posterior reversible encephalopathy syndrome (PRES) presents with seizures, altered consciousness/vision, nausea, vomiting, and focal neurological deficits.
• Imaging reveals bilateral, symmetrical brain edema, primarily in posterior regions, on MRI and CT scans.

Observation:

• A 73-year-old patient with hypertension and renal insufficiency developed PRES with occipital symptoms.
• CT and MR imaging confirmed white matter changes across all brain lobes.
• The patient received antihypertensive, hypolipemic, and rehydration therapy over two weeks.

Findings:

• Clinical improvement occurred without complications.
• Complete resolution of white matter changes was observed on follow-up CT and MR imaging.

Implications:

• PRES is a reversible condition requiring prompt diagnosis and treatment.
• Timely intervention facilitates symptom withdrawal and full radiological recovery.
