Questions about this test
Are swollen neck glands serious?
Most swollen neck glands are from infections such as a cold or sore throat and settle within a few weeks. A doctor should check glands that keep growing, feel hard, or last more than a few weeks.
Is a neck ultrasound the same as a thyroid ultrasound?
A thyroid ultrasound focuses on the thyroid gland, while a neck ultrasound looks more widely at lymph nodes, salivary glands and other lumps. They often overlap.
Can a neck ultrasound show TB glands?
Ultrasound can show swollen nodes with features that may suggest tuberculosis, but it cannot confirm it. A needle sample is usually needed to confirm the cause.
