VascularMultiple “mirror” aneurysms involving intracavernous carotid arteries and vertebral arteries: case report
Section snippets
Case report
A 54-year-old male experienced transient double vision and left facial dysesthesia in 1982. He developed worsening double vision again in December 1983, and was admitted to our hospital in March 1984. He was alert and exhibited no motor or sensory disturbances in the extremities. Moderate left forehead and ophthalmic pain was noted. Severe oculomotor palsy was observed on the left side, but light reflex was preserved bilaterally. Other cranial nerves including abducens and trochlear nerves were
Discussion
The characteristic anatomical structure of the intracranial arteries—that is, poorly developed external elastic lamina and adventitia, gaps in the muscular layer, and a great number of collagenous fibers—contributes to the formation of cerebral aneurysms. Indeed, previous reports concerning familial intracranial aneurysms 9, 13, 18, 22, 27 and recent experimental and clinical studies 1, 4, 6, 12, 17 have strongly suggested that a lack of connective tissue in the arterial wall is one of the

Current Management of Mirror Distal Anterior Cerebral Artery Aneurysms in Association with Multiple Aneurysms: Case Report with Literature Review
2019, World NeurosurgeryCitation Excerpt :According to our results, we found subarachnoid hemorrhage present in 22, and other sources of bleeding were found in 4 cases. Different studies hypothesize that an embryological, pre-existing defect of specific arterial segments could be the reason for the development of mirror aneurysms.38,39 One study lists smoking and hypertension among the risk factors,40 whereas some reports cited a decrease in the body mass index as a factor of aneurysm growth.41
Multiples of multiple: Case series of mirror aneurysms and review of literature
2019, International Journal of Surgery Case ReportsCitation Excerpt :Multiple sets of mirror aneurysms in the same patient are exceedingly rare. There are a total of 6 such case reports available in the literature to date [1,4,6–8]. We report 3 such patients amongst whom, one of them had 3 sets of mirror aneurysms and the other patient had 2 sets of mirror aneurysm on the same arterial segment which has not been reported till date.
Mirror Aneurysms among Multiple Aneurysms: Lesser of the Two Evils
2016, World NeurosurgeryCitation Excerpt :Patients with multiple aneurysms are a heterogenous group within the broader group of patients with intracranial aneurysms, accounting for 12.9%–26.4% of all aneurysms.7Among this group of cases, MirAn is a specific subset that occurs bilaterally on similarly named vessels. Literature about MirAns is scarce and to the best of our knowledge, only 3 large series comparing mirror and nMirAns have been reported, with other studies being either case reports or case series.6-12 MirAns frequently present with identical morphology, as shown in Figure 1; however, this was not always the case.
