Abstract:
Kissing aneurysms, a particular type of multiple aneurysm are rare. A kissing aneurysms was identified at the distal anterior cerebral artery (ACA) in a 59-year-old male patient diagnosed with subarachnoid hemorrhage (SAH). The use of three-dimensional intracranial CT angiograms revealed that kissing aneurysms (that is, an aneurysm with a bilateral symmetrical mirror image) were located at the distal ACA and diffuse SAH in basal, sylvian, and interhemispheric cisterns. Both conventional carotid angiograms showed that both distal ACA aneurysms were seen separately on both internal carotid angiograms. Two aneurysms were observed simultaneously on carotid compression of either side. Some particular cautions required in diagnosing and treating kissing aneurysms are discussed, together with a literature review.
