The localization of a cerebrospinal fluid fistula producing cerebrospinal fluid otorrhea can be very difficult. However, the exact anatomic localization of the bony defect is important when selecting the surgical approach to repair. Case reports of two patients in whom spontaneous cerebrospinal fluid otorrhea occurred following pressure equalization tube placement for middle-ear effusion are presented. Nuclear magnetic imaging supplemented CT scan findings, providing noninvasive localization of the defect. Preoperative impressions were confirmed at surgery. In addition to discussing the use of magnetic resonance imaging in evaluating cerebrospinal fluid otorrhea, the literature will also be reviewed.
定位导致脑脊液耳漏的脑脊液瘘可能非常困难。然而，在选择手术修复方法时，精确确定骨缺损的解剖位置很重要。本文介绍了两例因中耳积液放置压力平衡管后出现自发性脑脊液耳漏患者的病例报告。核磁共振成像补充了CT扫描结果，提供了缺损的无创定位。术前诊断在手术中得到证实。除了讨论磁共振成像在评估脑脊液耳漏中的应用外，还将对相关文献进行综述。
