A previously healthy 17-year-old male presented with sudden onset of painful right parotid swelling. It was sudden in onset without any history of trauma.  The patient developed deviation of the angle of mouth to the opposite side after 2 days of presentation. A diagnostic aspiration revealed low-flow blood which provided a direction to the final diagnosis of a venous malformation of the right parotid gland. Percutaneous sclerosant embolization with STS under ultrasound guidance was performed and the facial asymmetry with the parotid mass resolved completely within 6 weeks.
