Abstract

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.
