Abstract:
We describe a 54-year-old man with neurofibromatosis type 1 who presented with a left-sided neck mass. Computed tomography demonstrated a left common carotid artery aneurysm (51 × 33 mm). Surgery was performed because of the risk of rupture. The left common carotid artery was found to be a huge aneurysmal dilatation, and the arterial wall partially collapsed and extensively adherent to the surrounding tissues. Left common carotid artery to internal carotid artery bypass grafting was performed with a reversed saphenous vein graft. Histopathological examination revealed vascular fragility of the left carotid arterial wall.
