Abstract

Idiopathic hypertrophic pachymeningitis (IHP) is a chronic inflammatory disease of unknown cause. We report a case of IHP with bilateral distended subarachnoid space (SAS) of the optic nerves and unilateral visual disturbance. We observed marked amelioration of magnetic resonance (MR) imaging findings after initiation of treatment with prednisolone. This radiological finding implicates optic nerve sheath involvement that affects cerebrospinal fluid (CSF) dynamics around the optic nerve.

摘要

特发性肥厚性硬脑膜炎（IHP）是一种病因不明的慢性炎症性疾病。我们报告了一例 IHP 伴有双侧视神经鞘蛛网膜下腔（SAS）扩张和单侧视力障碍。我们观察到在开始使用泼尼松龙治疗后，磁共振成像（MR）检查结果明显改善。这种影像学发现提示视神经鞘受累，影响视神经周围脑脊液（CSF）动力学。
