Case Study
The article presents the case of a 66-year-old with bilateral dissection of internal carotid artery. It was pointed out dissection are frequent causes of onset stroke wherein it would be difficult to diagnose using only history and clinical signs. Fat saturated T1 weighted magnetic resonance was used in detecting the bilateral dissection.
