Ultrasound of Salivary Glands and the Non-endocrine Neck
It has become clear that management of thyroid disease, and especially thyroid cancer, requires familiarity with head and neck structures beyond the thyroid gland. A discussion of lymph node assessment and cervical lymph node mapping can be found in Chap. 8. Even the patient with thyroid disease may have inflammatory or malignant lymphadenopathy related to other head and neck structures. The clinician who performs ultrasonography of the thyroid gland will also, not infrequently, encounter pathology outside of the thyroid and the lymph nodes during scanning of the neck. The salivary glands are similar to the thyroid gland in many ways, including in their intermediate echogenicity and their (mostly) superficial position in the head and neck that makes them very accessible to ultrasound examination. The salivary glands are also susceptible to injury by 131I, and patients with thyroid cancer who have been treated with 131I may present with salivary gland complaints. This chapter will focus on salivary gland pathology and other pathologic entities within the head and neck region that may be encountered by the sonographer who is evaluating the patient with a known or suspected primary thyroid condition.
