Answer 55 = [1] Prednisolone
Posterior reversible encephalopathy syndrome (PRES) is a severe, life-threatening neurological disorder clinically presenting with various symptoms such as headache, visual disturbances, and epileptic seizures.
PRES is characterized by usually bilateral cerebral (parieto-occipital lobe) vasogenic edema in computed tomography (CT) and magnetic resonance imaging (MRI) scans and occurs most commonly in patients with uncontrolled hypertensive blood pressure.
Note >>> Greater than 90% of patients demonstrate involvement of the parietooccipital lobes, but lesion can also be present in the frontal lobe basal ganglia, cerebellum, and brainstem.
Steroids directly or indirectly causing acute HTN may lead to PRES.
