Ultrasound (US) is often the first modality utilized to characterize masses in the head and neck whether felt to be related to the thyroid or not. The superficial nature of these palpable lesions makes US especially suited for use in characterization as well as guiding fine needle aspiration, should imaging characteristics not be enough to direct management. A thorough history from the patient is also necessary to narrow the differential diagnosis of a head and neck lump.

Educational Goals / Teaching Points
After viewing this exhibit, the learner will • Understand the characteristics of benign and malignant neck lymph nodes • Describe the features of benign and malignant salivary gland masses • Differentiate parathyroid masses from thyroid masses • Recognize features of cystic neck masses that may be specific for particular entities • Determine when additional imaging or biopsy is needed

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
a. Nodes b. Salivary gland i. Pleomorphic Adenoma ii. Warthin iii. Adenoid Cystic Carcinoma iv. Other less common tumors c. Parathyroid d. Cystic masses e. Miscellaneous head/neck masses

Through a case-based approach, the learner will become more confident in his or her diagnosis of palpable head and neck masses outside of the thyroid.
