可逆性后部脑病综合征（PRES）的经典影像学表现为双侧顶叶和枕叶皮质下血管源性水肿，在文献中已得到充分证实。随着PRES经验的增长，越来越多地描述了各种各样的非典型表现。本图片回顾说明了PRES的各种表现，包括具有非典型影像学表现的病例。我们举例说明的情况下，PRES与不同分布的血管源性水肿，以及不典型的影像学表现，如变化的出血和限制扩散的情况下。在适当的临床情况下，不典型的影像学表现不应阻止PRES的诊断，并且对PRES的不同表现和不典型表现的了解使放射科医生能够做出这种诊断。
The classic imaging findings of posterior reversible encephalopathy syndrome (PRES) are of bilateral parietal and occipital subcortical vasogenic oedema, and are well established in the literature. As experience with PRES grows, varied and atypical presentations are being increasingly described. This pictorial review illustrates the variable presentations of PRES, including cases with atypical imaging findings. We illustrate cases of PRES with varying distributions of vasogenic oedema as well as cases with atypical imaging findings, such as variations of haemorrhage and restricted diffusion. Atypical imaging findings should not dissuade the diagnosis of PRES in the appropriate clinical situation, and knowledge of the varied appearance and atypical findings of PRES allows the radiologist to make this diagnosis.
