One-stage operation for rare multiple mirror intracranial aneurysms: a case report and literature review.

Although intracranial multiple aneurysms are not uncommon, multiple mirror aneurysms are relatively rare. A few isolated cases have been described. However, to the best of our knowledge, 3 pairs of pure symmetrical mirror aneurysms in one patient have not been reported yet. We present a case of multiple mirror aneurysms involving the bilateral middle cerebral artery (MCA) bifurcations and posterior communicating arteries (P-com A) confirmation by one-stage operation. The possibility of one-stage treatment must be considered before surgery. Missed diagnosis and misdiagnosis must be avoided before one-stage operation for multiple mirror aneurysms.
