Fusiform and dolichoectatic aneurysms
Fusiform (nonsaccular) aneurysms are elongated dilations of intracranial arteries lacking a distinct neck. Dolichoectasia can be used as an interchangeable term but can also describe a less severe spectrum of arterial dilation and/or tortuosity. Fusiform and dolichoectatic aneurysms can present with ischemic strokes, intracranial hemorrhage, or symptoms related to compression of cranial nerves or brain structures, but they are also often asymptomatic and detected incidentally.
