摘要

目的:报告3例原发性低颅压综合征（Primany intracraial hypotension

PIH）的磁共振成像（Magnetic resonance imaging

MRI）及临床表现特点

提出其诊断要点及检查注意点。方法:回顾性分析3例原发性低颅压综合征患者的MRI及临床表现特征。结果:颅脑MRI示2例硬脑膜弥散性强化;1例小脑扁桃体下移位

桥前池、枕大池变窄。2例脊髓MRI示:多序列多方位上蛛网膜下腔均变窄

境界不清

分别位于T5～T7、T8～T9节段

表现为硬膜外条状、弧形脑积液信号影。腰穿结果提示:3例病人脑脊液压力均低于60mmH2O。结论:体位性头痛是原发性低颅压综合征患者最典型的临床表现

硬脑膜弥散性强化是最常见的MRI表现

颅脑MRI增强扫描与常规脊髓MRI检查相结合有助于本病的诊断及病因的查找。

Abstract

Objective:Toreport the MRI characteristics and clinical manifestation in 3 cases ofprimaryintracranial hypotension syndrome(PIH)and put forward the main points in its diagnosis and examination.Methods:The MRI characteristics and clinical manifestation in 3 cases diagnosed as PIH were retrospectively analyzed.Results:The brain MRI found diffuse pachymeningeal gadolinium enhancement in 2 cases

downward displacement of amygdala cerebelli and narrowing of pontine cistern and cisterna magna in 1 case.In 2 cases by spinal cord MRI

subarachnoid cavity became narrow in multi-series and multi-aspect scanning and it’s boundary became unclear;one was located on T5～T7level and the other on T8～T9level;epidural collection of fluid showed strip or comma shape.All the 3 cases had lower CSF pressure(<60 mmH2O).Conclusion:Postural headache is the most characteristic symptom clinically in PIH

and diffuse pachymeningeal gadolinium enhangcement is the common MRI manifestation.A combination of brain MRI with the common spinal cord MRI in PIH conduces to clinical diagnosis.
