目的:探讨低颅压综合征(SIH)的临床特点和影像学改变。方法:回顾性分析12例SIH患者的临床及影像资料。结果:所有患者均有体位性头痛;头颅CT报告2例硬膜下积液;3例行头颅MRI检查示硬脑膜增厚;全部患者采用内科综合疗法,均痊愈。结论:SIH的临床表现多样,体位性头痛是特征性症状,腰穿脑脊液(CSF)及头颅MRI检查具有诊断价值;本病预后良好,但少数并发硬膜下血肿。
Objective: To investigate the clinical characteristics and imaging changes of low intracranial pressure syndrome (SIH). Methods: The clinical and imaging data of 12 patients with SIH were retrospectively analyzed. Results: All patients had positional headache; head CT scans showed 2 cases of subdural effusion; 3 cases of brain MRI showed dural thickening; all patients with medical therapy, were cured. CONCLUSIONS: The clinical manifestations of SIH are diverse. Posterior headache is a characteristic symptom. Diagnosing lumbar penetrating cerebrospinal fluid (CSF) and cranial MRI is of diagnostic value. The prognosis of this disease is good, but a few of the patients have subdural hematoma.
