前庭神经鞘瘤很常见，伽玛刀放射外科手术是有症状肿瘤的一种治疗选择。脑积水可能是伽玛刀治疗前庭神经鞘瘤的一种并发症，尽管因果关系可能存在争议，因为肿瘤在未经治疗的情况下也可导致脑积水。我们介绍了一例前庭神经鞘瘤伽玛刀放射外科手术后出现交通性脑积水的不寻常病例的磁共振成像研究，其中事件的时间线有力地表明伽玛刀在脑积水的发展中起到了促进作用。我们讨论了放疗后发生脑积水的风险因素，以及磁共振脑脊液电影血流研究在评估这种情况下脑积水治疗方案中的作用。
Vestibular schwannomas are common, and gamma knife radiosurgery is a treatment option of symptomatic tumors. Hydrocephalus may be a complication of gamma knife treatment of vestibular schwannoma, though the cause-and-effect relationship can be debated because tumors can cause hydrocephalus without treatment. We present an MR imaging study of an unusual case of communicating hydrocephalus after gamma knife radiosurgery of a vestibular schwannoma in which the timeline of events strongly suggests that gamma knife played a contributory role in the development of hydrocephalus. We discuss risk factors for the development of hydrocephalus after radiation therapy and the role of MR CSF cine-flow study in the evaluation of treatment options for hydrocephalus in this setting.
