Findings: The history of radiation therapy prompted a doppler ultrasound evaluation of the carotid arteries. The doppler scan revealed concentric hypoechoic low grade stenosis (aprox 40%) of the right carotid bulb and the origin of the internal carotid artery. The digital substraction angiography confirmed the Doppler findings.
Diagnosis: Radiation induced stenosis of the carotid artery
Discussion: Radiation induced vasculopathy is well known. Patients that undergo neck irradiation are at a five-fold increased risk compared to non-irradiated patients of developing moderate to severe carotid artery stenosis (Moritz arch surg 1990).
