title: Internal carotid artery redundancy and dissection  in a young cocaine abuser.
abstract: Carotid artery redundancies are common findings on routine imaging studies and are usually considered to be benign variants. We present a case of a 40-year-old man, with a history of cocaine abuse, who was diagnosed with dissection of the right internal carotid artery and looping of the bilateral internal carotid arteries. This report attempts to highlight the possible association between carotid artery redundancy and dissection, especially in the context of vascular injury such as cocaine abuse, as in our case.
