Vertebral artery dissection and thrombosis

Case contributed by A.Prof Frank Gaillard


Adult patient with cervical spine trauma (MVA).



Case Discussion

CT scan of the cervical spine demonstrates unremarkable alignment, and no convincing fracture. 

MRI demonstrates extensive soft tissue high signal in the interspinous region (best seen on STIR) as well as high signal anteriorly in the C5/6 disk, with interruption of the anterior annular fibers consistent with disruption. 

The right vertebral artery demonstrates high signal on T2 and intermediate signal on T1 sequences, consistent with vertebral artery thrombosis, presumably due to traumatic vertebral artery dissection.
