Intracranial arterial aneurysms can pose life-threatening risks to patients, so understanding the cause and the progression of these lesions is important for choosing the right treatment. This Review argues that aneurysms are a symptom of an underlying vascular disease rather than constituting a disease on their own. The authors classify intracranial aneurysms by vessel wall pathology and demonstrate that knowledge of the morphology and pathology of this structure is important in determining the therapeutic approach.
