A 30-year-old woman suffered from acute vertebrobasilar stroke. Cranial tomography
(CT) scans showed multiple vertebral abnormalities suggestive of congenital spine
malformation, and angiographic CT revealed aneurysmal dilatations (ADs) at segment
V2 of both vertebral arteries (VAs). Dynamic neuroimaging tests including angiography
and angio-CT were performed and showed occlusion of both VAs at the point of the ADs
with contralateral rotation of the neck. The presence of a bony structure causing
the artery compression was excluded and embolic phenomena originating at the AD was
proposed as the likely source of stroke. Even if infrequent, the presence of craniocervical
anomalies should be considered in vertebrobasilar stroke of indeterminate etiology.
