Mirror image of bilateral DACA aneurysm with its successful surgical management.

Background: Among various locations of intracranial aneurysms reported in the literature, two different aneurysms situated symmetrically opposite on bilateral distal anterior cerebral arteries (DACA) are very rare.

Case Description: Here, we report a rare case of mirror image distal anterior cerebral aneurysm in a middle-aged male patient. The patient presented with severe headache and loss of consciousness. Angiography was done which suggested mirror imaging of two aneurysms located over both DACA. It was treated through microsurgical approach with a successful outcome.

Conclusion: Careful analysis of intracranial vasculature should be done using angiography, particularly in different views and stages to rule out multiple aneurysms at different locations in the same artery or at different arteries. Mirror images of bilateral DACA aneurysms are very rare. Fundamental surgical strategy of securing the parent artery and clipping the neck after meticulous dissection should be followed.
