Intratumoral hemorrhage in vestibular schwannomas is rare. Symptoms often have an acute onset and include headache, nausea, vomiting, vertigo, and depressed consciousness. Intratumoral hemorrhage is probably caused by vascular fragility associated with tumor characteristics and growth. With hemorrhage in VS being rare, repeated hemorrhage has only been reported twice, and on clinical grounds only. The present report details the case of acute neurological deterioration in a patient with repeated intratumoral hemorrhage inside a vestibular schwannoma with computed tomography and magnetic resonance imaging confirmation. To our knowledge, repeated hemorrhage in vestibular schwannoma with radiological confirmation has not been reported before.
前庭神经鞘瘤内的瘤内出血较为罕见。其症状通常为急性发作，包括头痛、恶心、呕吐、眩晕和意识障碍。瘤内出血可能是由与肿瘤特征和生长相关的血管脆弱性引起的。由于前庭神经鞘瘤内出血较为罕见，仅报道过两次且均为临床报道。本报告详细介绍了一例经计算机断层扫描和磁共振成像证实的前庭神经鞘瘤内反复瘤内出血导致患者急性神经功能恶化的病例。据我们所知，在此之前，尚未有影像学证实的前庭神经鞘瘤反复出血的报道。
