[摘 要] 目的:探讨非小细胞肺癌(non⁃small cell lung cancer,NSCLC)软脑膜转移(leptomeningeal metastases,LM)患者磁共
振(magnetic resonance,MR)测量视神经鞘直径(optic nerve sheath diameter,ONSD)和头颅外周脑脊液体积/全脑容积(peripheral
cerebrospinal fluid volume/intracranial volume,PCSFV/ICV)比值与脑脊液压力(cerebrospinal fluid pressure,CSFP)的相关性,评
估 ONSD 和 PCSFV/ICV 联合诊断 CSFP 升高的准确性。方法:共收集 63 例 NSCLC⁃LM 患者,所有患者同时进行视神经和颅脑
MR 扫描,测量双眼 ONSD、颅脑 PCSFV 和 ICV。随后对所有患者行腰椎穿刺测量 CSFP,并定期进行鞘内化疗。采用 Pearson
相关分析法分析 CSFP 与 MR 表现的相关性。通过受试者工作特征(receiver operating characteristic,ROC)曲线评估 ONSD 和
PCSFV/ICV联合诊断CSFP升高的准确性。结果:所有NSCLC⁃LM患者双眼平均ONSD与CSFP呈正相关(r=0.567,P < 0.001),
PCSFV/ICV 与 CSFP 呈负相关(r=-0.365,P=0.003)。ROC 曲线分析显示 ONSD、PCSFV/ICV 及 ONSD 联合 PCSFV/ICV 诊断颅
内高压(CSFP>15 mmHg)的性能分别为 0.81(95%CI:0.71~0.91)、0.76(95%CI:0.64~0.89)和 0.91(95%CI:0.84~0.99)。ONSD、
PCSFV/ICV 及 ONSD 联合 PCSFV/ICV 诊断颅内高压(CSFP>20 mmHg)的性能分别为 0.70(95%CI:0.58~0.82)、0.72(95%CI:
0.57~0.88)和 0.81(95%CI:0.70~0.93)。结论:经 MR 测量 ONSD 和 PCSFV/ICV 可以评估 NSCLC⁃LM 患者 CSFP 的变化,二者联
合能够提高诊断颅内高压的准确性,有较好的临床应用价值。

[Abstract] Objective:To explore the correlation between magnetic resonance(MR)findings[optic nerve sheath diameter(ONSD)
and peripheral cerebrospinal fluid volume/intracranial volume ratio(PCSFV/ICV)]and cerebrospinal fluid pressure(CSFP)in patients
with leptomeningeal metastases(LM)from non⁃small cell lung cancer(NSCLC). And to assess the diagnostic accuracy of combined
ONSD and PCSFV/ICV in diagnosing elevated CSFP. Methods:A total of 63 patients with NSCLC⁃LM were enrolled. Both optic nerve
and cranial MR scans were performed to measure bilateral ONSD,cranial PCSFV and ICV. Subsequently,CSFP was measured in all
patients through lumbar puncture,and intrathecal chemotherapy was administered regularly. Pearson correlation analysis was used to
analyze the correlation between CSFP and MR findings. The accuracy of combined ONSD and PCSFV/ICV in diagnosing elevated
CSFP was evaluated through receiver operating characteristic(ROC)curve analysis. Results:In patients with NSCLC⁃LM,the average
ONSD of bilateral eyes was positively correlated with CSFP(r=0.567,P < 0.001). PCSFV/ICV was negatively correlated with CSFP
(r=-0.365,P=0.003). ROC curve analysis showed that the performance of ONSD,PCSFV/ICV,and combined ONSD with PCSFV/ICV
in diagnosing intracranial hypertension(CSFP>15 mmHg)were 0.81(95%CI:0.71-0.91),0.76(95%CI:0.64-0.89),and 0.91(95%CI:
