因脑血管疾病(出血、栓塞、血管痉挛等)而致的脑血循障碍可出现类似耳源性颅内并发症的症状。文献中也有散在的颅内血肿和出血误诊为耳源性颅内并发症的报告。脑出血时引起的脑血循障碍症状多突然发生,出现剧烈头痛和呕吐、伴体温升高。脑血栓和长期血管痉挛引起的脑局部缺血症状可突然或逐渐发病,常在睡眠中或睡眠后发生,无头痛或头痛很轻,一般无脑膜刺激症状或很轻。关于耳源性颅内并发症与伴有胆脂瘤型中耳乳突炎患者的脑血管疾病引起脑血循障碍的鉴别较困难。作者们曾发现6例血管性疾病引起脑血循障碍而误诊为耳源性颅内并发症,女4男2,年龄25～57岁。入院时诊断:耳源性脑脓肿3例,脑膜脑炎1例,小脑脓肿1例
Cerebrovascular disease due to cerebrovascular disease (hemorrhage, embolism, vasospasm, etc.) may show symptoms similar to ototoxic intracranial complications. There are also reports of scattered intracranial hematomas and misdiagnoses of otogenic intracranial complications in the literature. Cerebral hemorrhage caused by cerebral blood flow disorder symptoms more than sudden, severe headache and vomiting, with body temperature increased. Cerebral thrombosis and long-term vasospasm caused by cerebral ischemia symptoms may be sudden or gradually onset, often occurs after sleep or sleep, no headache or headache is very light, usually no meningeal irritation or very light. Identification of cerebrovascular disease due to cerebrovascular disease in patients with otogenic intracranial complications and cholesteatoma with otitis media is more difficult. The authors have found that 6 cases of vascular disease caused by cerebral vascular disorder misdiagnosed as otogenic intracranial complications, 4 female 2, aged 25 to 57 years. Diagnosis at admission: 3 cases of otogenic brain abscess, 1 case of meningoencephalitis, 1 case of cerebellar abscess
