- Introduction The purpose of our study was to compare the
clinical characteristics and preferential localization of aneurysms
in three patient groups: single aneurysm, non-mirror
multiple aneurysms, and mirror aneurysms.
Methods We retrospectively reviewed the clinical and radiological
data of 2223 consecutive patients harboring 3068 aneurysms
registered at the Toronto Western Hospital between May 1994
and November 2010. The patients were divided into single, nonmirror
multiple, ormirror aneurysmgroups. Expected incidences
ofmirror aneurysms at each location were calculated on the basis
of the single aneurysm incidences at each location.
Results Patients with mirror aneurysms (n=197) did not differ
from patients with non-mirror multiple aneurysms (n=392) in
having female predominance (81.7 vs. 76.3 %) or a family
history of intracranial aneurysm (20.5 vs. 17.6 %). When
compared with expected incidences at each location, mirror
aneurysms were more frequently found at the cavernous internal
carotid artery (30 vs. 11.5 %) (p<0.0001). Mirror aneurysms
involving the posterior circulation were less frequent
(6.7 %) than aneurysms in the single (19.6 %) or non-mirror
multiple aneurysm groups (18.9 %) (p<0.05).
Conclusion Patients with mirror aneurysms had similar clinical
characteristics to non-mirror multiple aneurysm patients.
Mirror aneurysms showed a predilection for the cavernous
carotid artery, whereas they
