Paroxysmal hypertension (PH) can be associated with the carotid artery baroreceptors' failure due to past exposure to radiation treatment. This report presents a patient who experienced repeated PH episodes due to the direct massage of the carotid artery during Doppler ultrasound of the neck. The radiation damage to the carotid artery baroreceptors might have increased their hypersensitivity to the mechanical and ultrasonic stimulation during the diagnostic test, leading to the hypertensive episodes. Patients who had received radiation therapy for head-and-neck cancer and require Doppler ultrasound of the carotid artery should be monitored for PH by recording their blood pressure prior and after the test.
