硬脑膜动静脉畸形(AVM’s)是罕见的血管异常改变,占颅内AVM’s 的10%～15%,常累及海绵窦、横窦或乙状窦的硬脑膜壁。前颅窝的硬脑膜AVM’s 尤为罕见,几乎都累及筛板和大脑镰前部的硬脑膜。本文作者报告8例,其中男7例;女1例。年龄44～61岁,平均年龄52岁。大多数颅内硬脑膜AVM’s 会出现轻微头痛或自觉颅内杂音,有些始终无症状,引起颅内出血者很少。而前颅窝AVM’s 的脑内出血的发病率是非常高的。本组4例出现脑中风症状,1例出现癫痫大发作,两例没有脑内出血表现的患者,分别出现耳鸣和严重持续性
Dural arteriovenous malformations (AVM’s) are rare vascular abnormalities that account for 10% to 15% of intracranial AVM’s, often involving the dural wall of the cavernous sinus, transverse sinus or sigmoid sinus. Dural AVM’s are particularly rare in the anterior cranial fossa, involving almost all of the dura mater of the sieve plate and the front of the falx. The authors report 8 cases, including 7 males and 1 females. Age 44 to 61 years old, average age 52 years old. Most intracranial AVM’s have mild headache or conscious intracranial murmurs, some of which are asymptomatic and cause very few intracranial hemorrhages. The incidence of intracerebral hemorrhage in anterior cranial AVM’s is very high. The group of 4 cases of stroke symptoms, epileptic seizures occurred in 1 case, two patients without intracerebral hemorrhage showed tinnitus and severe persistent
