Despite extensive imaging, a source of bleeding is often not evident during the evaluation of patients with superficial siderosis (SS) of the central nervous system. An intraspinal fluid-filled collection of variable dimensions is frequently seen on spine MR imaging in patients with idiopathic SS. A similar finding has also been reported in patients with craniospinal hypotension. This review discusses the role of multitechnique imaging in the work-up of patients with SS and focuses on recent developments.
尽管进行了广泛的影像学检查,但在评估中枢神经系统浅表铁沉积症 (SS) 患者时,通常无法明确出血源。在特发性 SS 患者的脊柱 MRI 上,经常可见到脊柱内充满可变尺寸的液体的集合。在颅脊低血压患者中也有类似的发现。本文讨论了多技术成像在 SS 患者检查中的作用,并重点介绍了最新进展。
