RT Journal Article SR Electronic T1 Neuroimaging in Superficial Siderosis: An In-Depth Look JF American Journal of Neuroradiology JO Am. J. Neuroradiol. FD American Society of Neuroradiology SP 5 OP 14 DO 10.3174/ajnr.A1628 VO 31 IS 1 A1 N. Kumar YR 2010 UL http://www.ajnr.org/content/31/1/5.abstract AB SUMMARY: 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.
