Abstract

PURPOSE OF REVIEW

Superficial siderosis (SS) of the nervous system is often due to a dural pathology. This review focuses on recent developments related to the management of this subgroup of patients with SS.

RECENT FINDINGS

The presence of an epidural ventral spinal fluid collection in patients with SS is a clue to the presence of a diskogenic dural defect. The location of the defect is ascertained by a dynamic CT myelogram, which involves placing the patient in a prone position with hips elevated. This permits gravity-assisted preferential ventral localization of the contrast and active scanning during contrast injection facilitates a precise delineation of the initial point of contrast extravasation which localizes the defect.

SUMMARY

Diskogenic dural defects are commonly the underlying etiology for SS in patients with a ventral spinal fluid collection. A dynamic CT myelogram facilitates detection and subsequent repair of these defects, which arrests the continued low-grade subarachnoid bleeding.

摘要

综述目的

神经系统表面铁沉积症（SS）通常由硬脑膜病变引起。本综述聚焦于该类SS患者管理方面的最新进展。

最新发现

SS患者硬膜外腹侧脑脊液聚集提示存在椎间盘源性硬脑膜缺损。通过动态CT脊髓造影确定缺损位置，即让患者俯卧位并抬高臀部。这使得造影剂在重力作用下优先向腹侧聚集，且在注射造影剂时进行动态扫描有助于精确描绘造影剂外渗的起始点，从而确定缺损位置。

总结

椎间盘源性硬脑膜缺损通常是腹侧脑脊液聚集的SS患者的潜在病因。动态CT脊髓造影有助于检测并随后修复这些缺损，从而阻止持续的低级别蛛网膜下腔出血。
