The purpose of this review is to give a better understanding of the pathogenesis of cystic formations of the mobile spine (CYFMOS) and the correlating imaging findings. This would help with medical decision-making, given the plethora of conservative, interventional, and surgical treatment options.
There has been a general understanding that CYFMOS are associated with degenerative spine changes. More recent articles however have suggested that identifying detailed imaging characteristics can assist in determining outcomes when CYFMOS are treated with interventional percutaneous methods or surgical decompression with or without concomitant fusion. CYFMOS although uncommon are not a rare finding seen in the spine when there is a background of degenerative spine changes. These cystic lesions are generally symptomatic by exhibiting mass effect on adjacent structure. Most treatments are aimed at decompression by interventional percutaneous or surgical means. Various imaging characteristics of these CYFMOS described in this article including their signal intensity, presence of spinal instability, particular patterns of adjacent degenerative changes, and imaging changes following interventional treatments can help guide physicians when managing these cases.
本文旨在更好地理解活动脊柱囊性病变（CYFMOS）的发病机制及其相关影像学表现。鉴于保守、介入和手术治疗方法众多，这有助于临床医生做出医疗决策。
目前普遍认为 CYFMOS 与退行性脊柱改变有关。然而，最近的一些文章表明，识别详细的影像学特征可以帮助确定在采用介入性经皮方法或手术减压（伴或不伴融合）治疗 CYFMOS 时的结果。虽然 CYFMOS 并不常见，但在退行性脊柱改变的背景下，在脊柱中也并非罕见。这些囊性病变通常表现为对邻近结构的压迫效应而出现症状。大多数治疗方法旨在通过介入性经皮或手术手段进行减压。本文描述了这些 CYFMOS 的各种影像学特征，包括其信号强度、脊柱不稳定的存在、邻近退行性改变的特定模式以及介入治疗后的影像学变化，这些特征可以帮助医生在处理这些病例时提供指导。
