Atypical MRI presentation of posterior reversible encephalopathy syndrome with predominant brainstem involvement

We report here the case of a 80-year-old woman for the assessment of an acute confusional state since 2 days asssociated with diffuse and gradual headache. Brain MRI disclosed isolated hyperintense signal on fluid-attenuated inversion recovery sequence involving the medulla and the right inferior ce...

Description
Summary:We report here the case of a 80-year-old woman for the assessment of an acute confusional state since 2 days asssociated with diffuse and gradual headache. Brain MRI disclosed isolated hyperintense signal on fluid-attenuated inversion recovery sequence involving the medulla and the right inferior cerebellar peduncle with moderate swelling, consistent with vasogenic oedema, without abnormalities on diffusion-weighted imaging sequence. PRES diagnosis was suspected and antihypertensive therapy was introduced to achieve a blood pressure goal
