摘　　要：目的:分析原发性低颅压综合征(spontaneous intracranial hypotension,SIH)的MRI征象,提高对该病的诊断水平。方法:回顾性分析14例经临床证实的SIH的MRI表现。结果:本组14例SIH患者MRI表现包括:平扫未见明显异常者2例(14.29%);硬膜下积液7例(50.00%);硬膜下血肿2例(14.29%);脑下垂8例(57.14%);垂体增大4例(28.57%);静脉窦扩张5例(35.71%);硬脑膜弥漫性增厚强化14例(100.00%)。结论:SIH的MRI征象中,硬脑膜弥漫增厚强化的阳性率最高,对本病的诊断和鉴别诊断具有较大价值。Objective：Analyze the MRI manifestations of spontaneous intracranial hypotension （ SIH） to improve the diagnosis of the disease. Methods：MRI manifestations of 14 patients clinically confirmed SIH were retrospectively analyzed. Results：Of all 14 ca-ses’ MRI manifestations,2 cases （14. 29%） had no obvious abnormality in scanning;subdural fluid accumulation showed in 7 cases （50. 00%）;subdural hematoma in 2 cases （ 14. 29%）;sagging of brain in 8 cases （ 57. 14%）;pituitary hyperemia in 4 cases （28. 57%）;engorgement of venous structures in 5 cases （35. 71%）;enhancement of meninges in 14 cases （100. 00%）. Conclusion：Enhancement of meninges has the highest positive rate in all MRI signs,and has greater value for the diagnosis and differential diagnosis of spontaneous intracranial hypotension.
