Abstract

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.

Özet

Bilimsel zemin: Posterior reverzibl ensefalopati sendromu (PRES), çok farklı etyolojik nedenlere dayalı olarak ortaya çıkan, genellikle posterior parietal ve oksipital bölgelerde vazojenik ödem ile seyreden bir antitedir. Ancak beklenen lokalizasyonlar dışında atipik lokalizasyonları da tutabilir ve tekrarlayıcı olabilir. Olgular: Bu yazıda iki PRES olgusunun MRG bulguları sunulacaktır. İlk olgunun posterior alanlar tutulmadan izole frontal ve talamik tutulumu olup, diğer olgu ise rekürren PRES atakları ile başvuran hipertansif bir hasta idi. YORUM: PRES tipik MRG bulgularının tanısal olduğu klinik-radyolojik bir antitedir. Ancak beklenen anatomik lokalizasyonlar dışında tutulum ve rekürren ataklar şeklinde atipik prezentasyonları da olabilir. Bu durumlarda da MRG bulguları altta yatan etyolojik faktör ve hastanın kliniği ile birlikte değerlendirilmeli ve PRES ayırıcı tanıda mutlaka yer almalıdır.
