BACKGROUND
Spontaneous convexity SAH in the elderly has heretofore been of uncertain origin until several recent case reports have suggested cerebral amyloid angiopathy (CAA) as the etiology.
OBJECTIVE
To better appreciate the relationship of convexity SAH in the elderly to CAA.
METHOD
The case histories and MR imaging findings of 4 patients with spontaneous convexity SAH were examined.
RESULTS
T2*-weighted imaging at the time of symptomatic SAH demonstrated features of prior lobar hemorrhage, microbleeds, and/or superficial hemosiderosis fulfilling diagnostic criteria of CAA in all patients.
CONCLUSIONS
CAA may be the foremost cause of convexity SAH in the elderly.
背景
在一些近期病例报告提示脑淀粉样血管病（CAA）为病因之前，老年自发性凸面蛛网膜下腔出血（SAH）的病因一直不明。
目的
更好地了解老年凸面SAH与CAA的关系。
方法
检查了4例自发性凸面SAH患者的病历及磁共振成像（MR）表现。
结果
有症状SAH时的T2*加权成像显示，所有患者均有符合CAA诊断标准的既往脑叶出血、微出血和/或浅表性含铁血黄素沉积特征。
结论
CAA可能是老年凸面SAH的首要病因。
