Focal common carotid artery intramural haematoma.

Focal common carotid artery intramural haematomas are rare. A 50-year-old man with a spontaneous onset of tenderness in the region of the right common carotid artery presented to our hospital (Christchurch, New Zealand). Ultrasound and CT imaging were consistent for an intramural haematoma. He was treated with antiplatelet therapy. A follow-up MRA showed resolution of the haematoma. Focal common carotid artery intramural haematomas are rare but not to be overlooked. This case presents a cause for intractable spontaneous neck pain in the region of the common carotid artery. Given the risk of rupture through the intima and potential risk for stroke the current recommended treatment is controversial.
