Basilar artery fenestration and aneurysms

Case contributed by Dr Henry Knipe

Presentation

Unconscious collapse.

Patient Data

Age: 60
Gender: Female

Hyperdensity inseparable from the prepontine basilar artery, suspicious for aneurysm. No subarachnoid haemorrhage seen. 

Basilar artery fenestration with anteriorly (larger) and posteriorly projecting aneurysm at the vertebrobasilar junction. 

DSA (angiography)

DSA confirms basilar artery fenestration and aneurysm. 

Case Discussion

This patient went onto have a negative lumbar puncture, and the cause of the unconscious collapse was unknown at discharge. This finding is probably incidental. Basilar artery fenestration is not uncommon, and is usually an anatomical variant although there is an increased incidence of cerebral aneurysm
