Carotid artery dissection is one of the most important causes of cerebral stroke in young age. Although most cases of carotid artery dissection appear spontaneously, sometimes it may result from a microtrauma which the patient does not take seriously. This article reports a case of extracranial internal carotid artery dissection starting from intense swimming and manifesting itself only as neck swelling and neck pain.
