We describe a case of successful management of a growing basilar artery dissecting aneurysm by the Pipeline flow diversion embolization device (PED). A 48-year-old woman presented with severe headache, neck pain, and altered consciousness. Computed tomography showed subarachnoid hemorrhage located in basal cisterns, with a pontine infarct shown on magnetic resonance imaging. Digital subtraction angiography showed dissecting aneurysm of the trunk of the basilar artery, with growth over time on repeated imaging. Repeated imaging demonstrated growth in size of the aneurysm. The aneurysm was treated with PED with complete obliteration of the basilar artery aneurysm. Subsequent follow-up demonstrated good clinical recovery.
