Scientific BACKGROUND: Posterior reversible encephalopathy syndrome is an entity presenting with posterior parietal and occipital vasogenic edema which occurs based on various etiological factors. However, it can involve atypical localizations that are unexpected and can be recurrent.
Cases: In this article, we present the MRI findings of two cases with PRES. The former is a patient with frontal and thalamic involvement, in absence of posterior involvement, and the latter is a hypertensive patient with recurrent PRES attacks.
CONCLUSION: PRES is a clinicoradiologic entity with diagnostic MRI findings. However, there can be atypical presentations such as involvement of the unexpected anatomical localizations and recurrent attacks. In this case, MRI findings should be evaluated by taking the underlying etiological factor and the clinical findings into consideration and PRES should be in the differential diagnosis.
