Internal carotid artery dissection

Left internal carotid dissection in the cervical segment with true and false lumen seen.
Case Discussion
This case is atypical for an internal carotid dissection because the typical dissection includes occlusion and high signal T1 crescent sign within the wall of the vessel (hematoma). The only feature fitting carotid dissection is evidence of cerebral ischemia. A double barrel lumen as this case is a rare presentation possibly due to carotid dysplasia.
