Left jaw swelling. Targeted ultrasound of the patient's site of swelling demonstrates a 2.5 x 2.0 x 2.6 cm hypoechoic mass demonstrating internal vascularity. The lesion has a central linear hyperechoic band suggesting that this may represent an abnormal infiltrated lymph node. Limited evaluation of the left cervical lymph node demonstrates normal appearing lymph nodes.
2.6 cm left submandibular area soft tissue mass may represent an abnormal infiltrated lymph node. A soft tissues of the neck CT with intravenous contrast is recommended to evaluate the aerodigestive tract for a potential primary malignancy. This mass is also amenable to ultrasound guided percutaneous biopsy.
