Case ReportHistory
Exam
Prior Study
There is focal hyperdensity in the distal basilar apex consistent with acute thrombus.
There is no discernable cytogenic edema, and certainly no obvious edema to confirm stroke outside the treatment window.
CT Perfusion
1. Short segment acute thrombus is evident on the included head CTA located in the distal basilar apex.
2. Delayed PCA filling (prolonged TTP) is related to retrograde PCA filling from the circle of Willis.
3. Chronic reduced CBV is evident in the caudal Rt. cerebellum, but no discernable hyperacute stroke is evident.
Findings
CTA of the neck
There is a focal stenosis of the left vertebral artery at its origin. The stenosis measures <60%, with no post stenotic dilatation nor distal vessel collapse. There is no apparent ulceration or soft clot. This stenosis likely accounts for the delayed filling in the cerebellar circulation on CT perfusion. Whether it is the source for the likely embolic thrombus in the basilar apex is indeterminate.
No other abnormality is evident within the cervical vessels
