Facial nerve schwannomas (FNSs) are rare benign tumors arising from the Schwann cells of the sheath of the facial nerve. These tumors may arise anywhere along the course of the facial nerve. Owing to their rarity and nonspecific clinical and radiological presentations, the preoperative diagnosis of FNSs is exceedingly difficult. In this study, we present four cases of histopathologically proven extratemporal schwannomas and a solitary case of intratemporal schwannoma. The purpose of this study was mainly focused on analyzing the imaging findings of extratemporal and intratemporal schwannomas in an effort to better characterize these lesions preoperatively. An early diagnosis of FNSs is helpful for the management and rehabilitation of these cases.
面神经鞘瘤（FNSs）是起源于面神经鞘膜施万细胞的罕见良性肿瘤。这些肿瘤可发生于面神经走行的任何部位。由于其罕见性以及非特异性的临床和影像学表现，FNSs的术前诊断极其困难。在本研究中，我们报告了4例经组织病理学证实的颞外神经鞘瘤及1例颞内神经鞘瘤。本研究的目的主要是分析颞外和颞内神经鞘瘤的影像学表现，以便在术前更好地对这些病变进行特征性描述。FNSs的早期诊断有助于这些病例的治疗和康复。
