Pseudo-anévrisme post traumatique de la carotide externe

Pseudoaneurysm is due to a disruption in the arterial wall, secondary to inflammation, trauma or iatrogenic causes such as surgery, percutaneous biopsy or drainage. We report the case of a 37-year old patient, presenting with cervical swelling that had progressively evolved after penetrating cervical trauma occurred 8 months before. Doppler ultrasound supplemented by CT angiography confirmed the diagnosis of pseudoaneurysm of the left external carotid artery. The considerable development of sectional imaging techniques and of angiography has allowed easier diagnosis.
