Abstract

Perivascular spaces (PVS) are fluid-filled structures that form the immediate peripheral environment of small cerebral vessels. They are a central component of the glymphatic system, which plays a crucial role in maintaining cerebral homeostasis. Their involvement in central nervous system diseases is currently a major focus of research, particularly in neuroimaging. Pathological enhancement of PVS on post-contrast MRI sequences creates a distinctive pattern due to their topography. As with other intracranial enhancement patterns, a differential diagnosis approach can be applied to perivascular enhancement (PVE). However, it is particularly challenging due to the rarity and complexity of the conditions involved. This article aims to facilitate the recognition of PVE pattern, to highlight the various causal conditions and to propose a practical diagnostic approach.

血管周围增强模式:识别、诊断光谱和实用方法-图片综述。
血管周围间隙(PVS)是一种充满液体的结构,形成小脑血管的直接周围环境。它们是淋巴系统的核心组成部分,在维持大脑稳态中起着至关重要的作用。它们在中枢神经系统疾病中的作用是目前研究的主要焦点,特别是在神经影像学方面。病理增强的PVS造影后的MRI序列创建一个独特的模式,由于他们的地形。与其他颅内增强模式一样,鉴别诊断方法可应用于血管周围增强(PVE)。然而,由于所涉及的条件的稀有性和复杂性,这尤其具有挑战性。本文旨在促进对PVE模式的认识,突出各种病因,并提出一种实用的诊断方法。
