Twin Giant Intracranial Aneurysms.

Giant aneurysms of the intracranial vertebral artery and posterior inferior cerebellar artery are challenging to treat as they often necessitate direct sacrifice of the diseased segment, which is thought to carry high morbidity due to brainstem and cerebellar stroke. Here, we report images of twin giant aneurysms of the left posterior inferior cerebellar artery at the brainstem and cerebellopontine angle region in a young child.
