Abstract

Background: We aimed to evaluate the optic nerve and optic nerve sheath diameter of patients with idiopathic normal pressure hydrocephalus with magnetic resonance imaging and to compare with the normal population. Methods: Magnetic resonance images and clinical records of the patients were retrospectively evaluated between 01.01.2015 and 01.01.2020. Twenty one patients in the normal pressure hydrocephalus group and 47 patients in the control group were included. Measurements were performed from the images obtained by creating multiplanar reconstructions from thin-slice Fast Spin Echo T2-weighted images. Measurements were made of optic nerve from the 3 mm posterior to the optic globe, on the plane which is oriented perpendicular to the nerve. Results: There was no difference between the two groups in terms of optic nerve diameters. Optic nerve sheath diameters are significantly higher in the normal pressure hydrocephalus group (p<0.0001). Conclusion: Morphological analysis of the optic nerve sheath complex which contains cerebrospinal fluid will contribute to the diagnosis and understanding chronic effects of normal pressure hydrocephalus, a disease in which changes in brain compliance and cerebrospinal fluid absorption are suspected in its etiology.

磁共振成像对特发性常压脑积水患者视神经鞘复合体的评价

背景：我们旨在通过磁共振成像评估特发性常压脑积水患者的视神经和视神经鞘直径，并与正常人群进行比较。方法：回顾性分析2015年1月1日至2020年1月01日期间患者的磁共振图像和临床记录。包括21名正常压力脑积水组患者和47名对照组患者。通过从薄片快速自旋回波T2加权图像创建多平面重建而获得的图像进行测量。在垂直于神经定向的平面上，对视球后3mm的视神经进行测量。结果：两组视神经直径无明显差异。正常压力脑积水组视神经鞘直径明显较高（p＜0.0001）。结论：对含有脑脊液的视神经鞘复合体进行形态学分析将有助于诊断和了解正常压力脑出血的慢性影响，一种病因怀疑大脑顺应性和脑脊液吸收发生变化的疾病。

期刊介绍： Neurology Asia (ISSN 1823-6138), previously known as Neurological Journal of South East Asia (ISSN 1394-780X), is the official journal of the ASEAN Neurological Association (ASNA), Asian & Oceanian Association of Neurology (AOAN), and the Asian & Oceanian Child Neurology Association. The primary purpose is to publish the results of study and research in neurology, with emphasis to neurological diseases occurring primarily in Asia, aspects of the diseases peculiar to Asia, and practices of neurology in Asia (Asian neurology).
