Involvement of the coronary artery is very rare but may cause life-threatening spontaneous dissection. Because it is rare, this disease may go unrecognized. A unique angiographic finding of non-coronary arteries can make an early diagnosis, and prompt treatment is paramount. In this paper, we report on a multiple vessel coronary artery dissection in a female patient who presented with acute stroke symptoms secondary to spontaneous dissection of the left vertebral artery. To date, this is the first case report of the spontaneous dissection of six branches of coronary arteries and the vertebral artery due to fibromuscular dysplasia.
