BACKGROUND
We report a case of acute subdural hematoma (SDH) due to angiographically unvisualized ruptured aneurysm.
CASE DESCRIPTION
A 57-year-old man presented with sudden-onset headache and nausea. Computed tomography revealed right acute SDH and cerebral angiography revealed no abnormal vessels, but at operation, we found an aneurysm arising from the precentral artery causing an acute SDH.
CONCLUSION
In a case of spontaneous acute SDH, the possibility of a cortical artery aneurysm should be considered even if no aneurysm is recognized at angiography.
背景
我们报告一例因血管造影未显影的破裂动脉瘤导致的急性硬膜下血肿（SDH）病例。
病例描述
一名57岁男性突发头痛和恶心。计算机断层扫描显示右侧急性硬膜下血肿，脑血管造影未发现异常血管，但手术时我们发现中央前动脉有一个动脉瘤，导致急性硬膜下血肿。
结论
在自发性急性硬膜下血肿的病例中，即使血管造影未发现动脉瘤，也应考虑皮质动脉动脉瘤的可能性。
