title: Unusual aneurysms.
abstract: Cerebral aneurysms can present in a variety of special circumstances. Aneurysmal subarachnoid hemorrhage (SAH) can complicate systemic or neoplastic disease, head injuries, arterial dissection, and other cerebrovascular conditions. Aneurysms associated with non-saccular configuration or giant size can make surgical or endovascular intervention difficult if not impossible. This article will review these uncommon aneurysms and their management.
