title: Recurrent subarachnoid haemorrhage from a de novo basilar bifurcation aneurysm: a case report.
abstract: Well documented cases of posterior circulation de novo aneurysms are rare. We report a patient who recently presented following a third episode of aneurysmal subarachnoid haemorrhage. Subsequent cerebral angiography revealed a basilar bifurcation aneurysm. This was absent on previous angiographic studies. The current literature on de novo aneurysms is reviewed. The implications for screening are considered.
