Hemorrhagic vestibular schwannoma (HVS) consisting of acute intratumoral and subarachnoid hemorrhage presents with acute nausea, vomiting, facial numbness, headache, loss of consciousness, and significant functional impairment of the facial and vestibulocochlear nerves. The current case is of a 31-year-old man who was presented with acute left lateral suboccipital headache, vomiting, ataxia, and loss of consciousness. Brain CT revealed a large iso-intense lesion with internal hematoma at the left cerebellopontine angle in association with internal acoustic canal dilation. In addition, MRI confirmed a 32 x 25 x 26 mm vestibular schwannoma (VS) with 20 x 15 x 5 mm intratumoral hematoma. The patient had undergone left lateral suboccipital craniotomy and microscopic tumor resection. Pathological findings revealed that his lesions were VS. The average incidence of HVS is around 2.15 cases per year worldwide. Therefore, HVS incidence in proportion to VS is very low and consequently rare.
出血性前庭神经鞘瘤（HVS）由急性瘤内和蛛网膜下腔出血组成，表现为急性恶心、呕吐、面部麻木、头痛、意识丧失以及面神经和前庭蜗神经的严重功能障碍。本例为一名31岁男性，出现急性左侧枕下头痛、呕吐、共济失调和意识丧失。脑部CT显示左侧小脑脑桥角有一个大的等密度病变，伴有内部血肿，同时伴有内耳道扩张。此外，MRI证实有一个32×25×26mm的前庭神经鞘瘤（VS），伴有20×15×5mm的瘤内血肿。患者接受了左侧枕下开颅和显微镜下肿瘤切除术。病理结果显示其病变为VS。全球范围内，HVS的平均发病率约为每年2.15例。因此，HVS在VS中所占比例非常低，因而较为罕见。
