【摘要】 目的分析低颅压综合征的临床特点与MRI诊断价值。 方法回顾性分析经腰穿测压证实的12例低颅压综合征患者的临床和MRI表现。 结果本组12例低颅压综合征患者中均有特征性的体位性头痛,12例患者CSF压力<60 mmH₂O。MRI表现包括弥漫性硬脑膜强化12例;脑下垂5例;硬膜下积液4例;硬膜下血肿2例。 结论低颅压综合征的MRI表现具有特征性,尤其是增强后硬脑膜弥漫强化征象对本病的诊断很有价值。

    【Abstract】 ObjectiveTo analyse the clinical characters and diagnostic value of MRI of Intracranial hypotension syndrome. MethodsThe clinical and MRI findings of 12 cases with intracranial hypotension syndrome confirmed by lumbar puncture were retrospectively analysed. ResultsThe typical orthostatic headache were presented in 12 patients.CSF pressurewere below 60 mmH₂O in all patients,MRI findings of Intracranial hypotension syndrome including:diffuse enhancement of the pachymeningesin 12 cases; sagging of the brain in 5 cases;subdural effusion in 4 cases;subdura lhematoma in 2 cases. ConclusionMRI findings of intracranial hypotension syndrome are characteristic,especially the finding of diffuse enhancement of the pachymeninges is valuable in diagnosing intracranial hypotension syndrome. ...... 濡傛灉鎮ㄥ湪浣跨敤鎵嬫満绛夋祦瑙堟椂鏃犳硶鏌ョ湅鎴栦笅杞藉叏鏂囷紝鍙兘鏄鎼滅储寮曟搸澶辩湡鈥滆浆鐮佲€濓紝璇风偣鍑诲睆骞曟渶涓嬫柟鐨勨€滅數鑴戠増鈥濇垨鈥滃師缃戦〉鈥濊闂€�
