that leads to the development of characteristic collateral vessels seen on cerebral angiography. MMD is commonly
accompanied by intracranial aneurysms; however, the current literature is sparse regarding the best available
treatment options for aneurysms in patients with MMD. Long-term angiographic outcome is also not well established.
Case description: We report the safety and efficacy of stent-assisted coiling in an adult Indian woman of unilateral
hemorrhagic MMD having a large asymptomatic cavernous segment aneurysm on the contralateral side. The patient
had excellent angiographic occlusion without any recurrence/hemorrhage in the 5-year follow-up after the
procedure.
Conclusion: MMD should be kept in mind in evaluating patients presenting with cerebrovascular accidents.
The case strengthens the view that stent-assisted coil embolization of large saccular aneurysms around the
circle of Willis is a viable minimally invasive therapeutic option in such unusual patients.
