Posterior reversible leukoencephalopathy syndrome (PRES) is classically characterized by headache, confusion, seizure, visual loss, and imaging findings of bilateral cortical and subcortical vasogenic edema in the posterior circulation area. We present three cases of PRES with different clinical and/or imaging features. They were associated with pregnancy. First case was a typical PRES, second case’s lesions were predominantly in the anterior circulation area of the brain, and third case was hemorrhagic PRES. Different clinical and/or radiological features can be seen in cases with PRES.
