The most common cerebellopontine angle (CPA) tumor is a vestibular schwannoma, but one in five CPA tumors are not vestibular schwannomas. These tumors may require different management strategies. Compared with vestibular schwannomas, symptoms and signs from cranial nerve VIII are less frequent: other cranial nerve and cerebellar symptoms and signs predominate in patients with these less common CPA tumors. Computed tomography and magnetic resonance imaging often show features leading to the correct diagnosis. Treatment most often includes surgery, but a policy of observation or subtotal resection is often wiser. This review provides a structured approach to the diagnosis of nonvestibular schwannoma CPA lesions and also management guidelines.
最常见的桥小脑角(CPA)肿瘤是前庭神经鞘瘤,但五分之一的CPA肿瘤并非前庭神经鞘瘤。这些肿瘤可能需要不同的治疗策略。与前庭神经鞘瘤相比,来自第八对脑神经的症状和体征较少见:在这些不太常见的CPA肿瘤患者中,其他脑神经和小脑的症状及体征更为突出。计算机断层扫描和磁共振成像通常显示出有助于正确诊断的特征。治疗通常包括手术,但观察或次全切除策略往往更为明智。本综述提供了一种诊断非前庭神经鞘瘤CPA病变的结构化方法以及治疗指南。
