Symptomatic vestibular schwannomas can be treated with resection (translabyrinthine, retrosigmoid [suboccipital], or middle cranial fossa approaches) or stereotactic radiosurgery. When appropriate, auditory brainstem stimulators can also be implanted in patients with current or impending hearing loss due to bilateral vestibular schwannomas. Imaging plays a prominent role in determining management following these procedures. In this article, the expected postoperative imaging appearances are depicted. The radiological features of complications are also reviewed, including recurrent tumor, fat graft necrosis, CSF leakage, infection, hydrocephalus, cerebral infarction, venous sinus thrombosis, hemorrhage, and temporal lobe and cerebellar contusions.
有症状的前庭神经鞘瘤可通过切除（经迷路、乙状窦后 [枕下 ]、中颅窝入路）或立体定向放射外科治疗。当情况合适时，由于双侧前庭神经鞘瘤导致的当前或即将发生的听力损失的患者也可以植入听觉脑干刺激器。成像在确定这些手术后的管理中起着重要作用。在本文中，描述了预期的术后成像表现。还回顾了并发症的放射学特征，包括复发性肿瘤、脂肪移植物坏死、CSF 漏、感染、脑积水、脑梗死、静脉窦血栓形成、出血以及颞叶和小脑挫裂伤。
