多数情况下,颅内动脉瘤破裂在 CT 上的特征性表现为蛛网膜下腔出血(SAH),可伴有脑内出血(IPH)、脑室内出血(IVH)或硬膜下出血(SDH)。但少数情况下,也可仅表现为 IPH、IVH 或 SDH,而无SAH 的发生。作者总结13例无 SAH 的破裂动脉瘤资料,复习文献对相关问题进行探讨。临床资料1991年1月到2004年6月期间共收治822例确诊为动脉瘤破裂患者,其中13例 CT 扫描上仅表现为 IPH 或(和)IVH 而无 SAH。13例中9例仅表现为 IPH,3例仅表现为 IPH 和 IVH,1例仅表现为
In most cases, intracranial aneurysm rupture is characterized by subarachnoid hemorrhage (SAH), which can be associated with intracerebral hemorrhage (IPH), intraventricular hemorrhage (IVH) or subdural hemorrhage (SDH). But in a few cases, it can also only appear as IPH, IVH or SDH without SAH. The authors summarize 13 cases of aneurysm without SAH data, review the literature to explore the related issues. Clinical data A total of 822 patients with ruptured aneurysms were treated during January 1991 to June 2004, 13 of whom showed only IPH or (and) IVH without SAH on CT scans. Of the 13 cases, only 9 cases showed IPH, 3 cases showed only IPH and IVH, 1 case showed only
