A: Axial noncontrast computed tomography (CT) demonstrates a sizable volume of subarachnoid hemorrhage centered in the suprasellar cistern with extension into the interhemispheric fissure and Sylvian fissures. A: Axial noncontrast computed tomography (CT) demonstrates a sizable volume of subarachnoid hemorrhage centered in the suprasellar cistern with extension into the interhemispheric fissure and Sylvian fissures. B: Axial maximum intensity projection reconstruction from a corresponding CT angiogram shows 2 aneurysms arising from the left anterior cerebral artery (straight arrow and curved arrow). C: Three-dimensional reconstruction from a follow-up catheter-based digitally subtracted angiogram shows the proximity of the 2 lesions (straight arrow and curved arrow). Andrew J. Steven et al.
