Aneurysmal rupture during angiography

A case of rupture, during angiography, of a right middle cerebral artery aneurysm with profuse hemorrhage into the subarachnoidal space is presented. Bleeding must have started between the two injections for the frontal and for the lateral carotidograms. The aneurysm that ruptured two days after a closed cerebral trauma was probably traumatic in origin.
