Abstract
Posterior reversible encephalopathy syndrome [PRES] is a reversible clinico-radiological syndrome characterized by headache, seizures, altered consciousness and visual disturbances. It has association with many causes. A significant relationship with acute hypertension is found. Multiple theories are proposed for explaining pathophysiology. MRI is the gold standard for diagnosis. Early detection and immediate treatment helps in full recovery. Our aim is to discuss PRES in detail with the help of a case of a young lady with pre-eclampsia diagnosed with PRES. Reversibility of clinical features and characteristic MRI findings lead to the diagnosis. Patient fully recovered with conservative management. PRES is a rare but possible cause of vision loss.
