Spontaneous rupture of the carotid artery is rare, however, it is a fatal injury and early diagnosis is very important. We expe-rienced a 54-year-old male patient who presented to the emergency department with an expanding neck mass after cough. Rupture of the common carotid artery 2 cm before bifurcation with a pseudoaneurysm was diagnosed on neck computed tomography angiography. Focal tear of the artery was repaired surgically with suture. Herein, we report on a rare occurrence of a spontaneous carotid artery rupture and review other reports.
