摘要

我们报告了一例 80 岁女性患者的巨大前庭分裂瘤病例，该瘤在姑息性伽玛刀放射外科手术（GKS）后缩小。神经系统症状包括听力衰退和面部麻痹。肿瘤体积为 21.9 毫升。开颅手术被认为是高风险手术，而传统的伽玛刀放射外科手术由于存在一过性增大的风险，也有一定的风险。因此，只对部分肿瘤进行了 GKS。边缘剂量（12 Gy）体积为 3.8 mL（17.4%）。肿瘤在短暂增大后开始缩小。60 个月后，肿瘤体积仅为 3.1 mL，患者无需进行挽救性治疗即可维持独立的日常生活。

Palliative Gamma Knife Radiosurgery for a Small Part of a Large Vestibular Schwannoma in an Elderly Patient.

We report a case of a large vestibular schwannoma in an 80-year-old female patient that shrank after palliative Gamma Knife radiosurgery (GKS). Neurological symptoms included hearing deterioration and facial palsy. The tumor volume was 21.9 mL. Craniotomy was considered high-risk, and conventional GKS was risky, owing to the risk of transient enlargement. Therefore, GKS was performed on only a portion of the tumor. The marginal dose (12 Gy) volume was 3.8 mL (17.4%). The tumor began to shrink after transient enlargement. Sixty months later, the tumor volume was only 3.1 mL, and the patient was able to maintain independent activities of daily living without salvage treatment.
