Presentation
Headache and vomiting.
Patient Data
No intracranial bleeding. No mass or midline shift.
No hydrocephalus.
Marked stenosis of the right vertebral artery (segment V2) with luminal irregularities, as well as thickening of the arterial wall (probable luminal thrombosis). There is no mural hyperdensity.
The rest of the supra-aortic and intracranial arteries are unremarkable.
T1 hyperintensity in the wall of the right vertebral artery (segment V2).
No ischemic stroke or bleeding.
No midline shift or brain herniation. No hydrocephalus.
Case Discussion
In this case, there was no history of trauma or neck manipulation, and the cause of the vertebral dissection remains unknown, probably due to sudden movements since the patient does not have connective tissue disease or fibromuscular dysplasia explaining the arterial dissection.
