Patients with neurofibromatosis have an increased incidence of acoustic neuroma, which is often bilateral. We present three patients with neurofibromatosis and enlarged internal auditory canals secondary to dural ectasia, without associated acoustic neuromata. Air CT cisternography and Metrizamide CT cisternography was needed in differentiating dural ectasia from acoustic neuroma in two patients.
患有神经纤维瘤病的患者听神经瘤发病率增加，且常为双侧性。我们报告了3例患有神经纤维瘤病且因硬脑膜扩张继发内耳道扩大的患者，并无相关听神经瘤。两名患者需要通过空气CT脑池造影和甲泛葡胺CT脑池造影来鉴别硬脑膜扩张与听神经瘤。
