目的:探讨成人出血型烟雾病的影像学表现及临床特征。方法:18例患者均经头部CT检查诊断为颅内出血,经全脑血管造影检查确诊。结果:18例出血型烟雾病中,CT表现为脑室出血者为9例,蛛网膜下腔出血者5例,脑实质出血者4例,脑血管造影均累及单侧、双侧颈内动脉及其分支,其病变区域均有烟雾状血管网形成。结论:对于年龄较轻的脑出血患者,尤其是脑室及蛛网膜下腔出血者,应考虑出血型烟雾病的可能。CT及脑血管造影是诊断烟雾病的主要手段。
Objective: To investigate the imaging features and clinical features of adult haemorrhagic moyamoya disease. Methods: Eighteen patients were diagnosed as intracranial hemorrhage by head CT examination and confirmed by whole cerebral angiography. Results: Among the 18 cases of haemorrhagic moyamoya disease, CT showed ventricular hemorrhage in 9 cases, subarachnoid hemorrhage in 5 cases, cerebral parenchymal hemorrhage in 4 cases, cerebral angiography involving both unilateral and bilateral internal carotid artery and Its branches, the lesion area has a smoke-like vascular network. Conclusion: For younger patients with cerebral hemorrhage, especially in patients with intraventricular and subarachnoid hemorrhage, the possibility of bleeding moyamoya disease should be considered. CT and cerebral angiography is the main means of diagnosis of moyamoya disease.
