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.
