Patients infected with the human immunodeficiency virus (HIV) or suffering from acquired immunodeficiency syndrome (AIDS) are now surviving for longer periods of time secondary to improvements in medical management. As the classical causes of morbidity and mortality in this patient population have come under better control, new complications are becoming more prevalent. In our clinical practice, there appears to have been a rise in the number of patients with HIV infection and AIDS who have experienced aneurysmal subarachnoid hemorrhage (SAH). In this paper, we review the available literature regarding cerebral aneurysms in patients infected with HIV and/or suffering from AIDS.
