The CT findings in 19 cases of ruptured anterior communicating artery aneurysms are analyzed and compared to the angiographic appearance. Observations from this series and literature review include (a) occasional negative scans, (b) visualization of non-giant aneurysms on infused axial scans, (c) common asymmetric subarachnoid hemorrhage, (d) involvement of the anterior interhemispheric fissure whenever subarachnoid hemorrhage is visualized, (e) "typical" septal hematoma in a minority of cases, (f) frequent infarction, particularly in the anterior cerebral artery distribution, (g) "meningeal hyperemia" seen on post-contrast scans, and (h) little correlation between angiographic aneurysm orientation and the location of hemorrhage on CT scan.
分析19例前交通动脉动脉瘤破裂的CT表现，并与血管造影表现进行比较。该系列观察结果及文献综述包括：(a)偶尔出现扫描阴性；(b)在增强轴位扫描上可显示非巨大动脉瘤；(c)常见不对称蛛网膜下腔出血；(d)只要有蛛网膜下腔出血，前半球间裂就会受累；(e)少数病例出现“典型”的间隔血肿；(f)频繁梗死，尤其是在前脑动脉分布区；(g)增强扫描可见“脑膜充血”；(h)血管造影动脉瘤的方向与CT扫描上出血部位之间几乎没有相关性。
