The purpose of our study was to evaluate the characteristic findings of acute hemorrhage due to amyloid angiopathy with computed tomography. 14 patients of intracranial hemorrhage with histologically confirmed cerebral amyloid angiopathy were observed over a period of 4 years. Characteristic findings were a lobar hemorrhage in superficial localisation, cortical involvement, subarachnoid hemorrhage, the multiplicity of hemorrhages and repeated episodes. Severe cerebral amyloid angiopathy is often accompanied by multiple petechial hemorrhages, restricted to a cortical-subcortical distribution, detectable by magnetic resonance imaging. These findings suggest that cerebral amyloid angiopathy is not a rare cause of atraumatic lobar hemorrhage. Amyloid angiopathy should be considered in any elderly patient with superficial intracerebral hemorrhage in an atypical location.
我们研究的目的是通过计算机断层扫描评估淀粉样血管病所致急性出血的特征性表现。对14例经组织学证实为脑淀粉样血管病的颅内出血患者进行了为期4年的观察。特征性表现为表浅部位的脑叶出血、皮质受累、蛛网膜下腔出血、出血的多发性和反复出血发作。严重的脑淀粉样血管病常伴有多发性瘀点样出血，局限于皮质 - 皮质下分布，可通过磁共振成像检测到。这些发现表明，脑淀粉样血管病是非创伤性脑叶出血的一个并不罕见的病因。对于任何在非典型部位发生表浅脑出血的老年患者，都应考虑淀粉样血管病。
