Surgical Management of a Ruptured Posterior Choroidal Intraventricular Aneurysm Associated with Moyamoya Disease Using Frameless Stereotaxy: Case Report and Review of the Literature

The management of hemorrhagic moyamoya disease should be modified based on the source of hemorrhage and its relation to a specifically located aneurysm. In the case of aneurysms arising from the choroidal artery, the general belief is that most of these represent pseudoaneurysms and have a tendency to regress spontaneously. Because of the rebleeding risk, we recommend early intervention in treating ruptured intracranial aneurysms using the least invasive surgical techniques.
