Posterior reversible encephalopathy syndrome (PRES) is a clinico-radiologic syndrome resulting in subcortical vasogenic edema appreciated on T2/fluid-attenuated inversion recovery (FLAIR) sequence of magnetic resonance imaging (MRI). PRES classically involves bilateral parieto-occipital lobes and is usually reversible. Atypical variant of PRES includes the involvement of brainstem, basal ganglia, thalami, or periventricular white matter. We report an unusual case of PRES with isolated brainstem involvement with periventricular white matter changes in a patient with renovascular hypertension from unilateral renal artery stenosis. To our knowledge, this is the first case of secondary hypertension from renal artery stenosis resulting in the atypical variant of PRES.
后部可逆性脑病综合征（PRES）是一种临床放射学综合征，在磁共振成像（MRI）的T2/液体衰减反转恢复（FLAIR）序列上表现为皮质下血管源性水肿。PRES典型地累及双侧顶枕叶，通常是可逆的。PRES的非典型变体包括脑干、基底神经节、丘脑或脑室周围白质受累。我们报告了一例不寻常的PRES病例，该病例为一名单侧肾动脉狭窄所致肾血管性高血压患者，仅脑干受累并伴有脑室周围白质改变。据我们所知，这是首例由肾动脉狭窄导致继发性高血压并引起PRES非典型变体的病例。
