An unusual case of CSF leak from the nontumor ear after removal of a 3-cm acoustic neuroma is presented. Prior to tumor removal a ventricular-peritoneal shunt was established because of increased intracranial pressure. After the shunt was clamped the patient twice developed rhinoliquorrhea and underwent in both instances unsuccessful closure of the leak on the tumor side. Finally the leak was established in the nontumor ear, most likely due to sequelae after a hunting accident 20 years before, where a projectile created a defect in the tegmen tympani. The CSF leak was probably provoked by the pressure changes following tumor removal and shunt treatment.
本文报告了一例罕见病例，患者在切除3厘米听神经瘤后，非肿瘤侧耳朵出现脑脊液漏。在肿瘤切除术前，由于颅内压升高，已建立了脑室-腹腔分流术。分流管夹闭后，患者两次出现鼻漏，且两次尝试封堵肿瘤侧漏口均未成功。最终确定漏口位于非肿瘤侧耳朵，很可能是20年前一次狩猎事故的后遗症，当时一枚射弹造成了鼓室盖的缺损。脑脊液漏可能是由肿瘤切除和分流治疗后的压力变化引发的。
