Giant Basilar Artery Aneurysm: Pathophysiology, MRI Diagnosis, Imaging Features, Treatment, and Prognosis | Neurovascular Imaging Review
Giant Basilar Artery Aneurysm: Pathophysiology, MRI Diagnosis, Imaging Features, Treatment, and Prognosis | Neurovascular Imaging Review Introduction: Giant Basilar Artery Aneurysm as a Critical Neurovascular Emergency The Giant Basilar Artery Aneurysm represents one of the most complex and life-threatening entities in neurovascular medicine. This rare but devastating form of intracranial aneurysm arises within the basilar artery, the central vessel supplying the brainstem, cerebellum, and posterior cerebral circulation. Due to its location within the posterior circulation, even gradual enlargement may result in severe neurological deterioration, while rupture can lead to catastrophic subarachnoid hemorrhage and death. The present case involves a 47-year-old right-handed woman presenting with progressive occipital headache, cognitive impairment, and personality change, with imaging revealing a giant basilar artery aneurysm measuring approximately 3.5 × 4.0 cm.
