What should you know?
Thyroid enlargement can be diffuse or nodular; hormone function cannot be determined by ultrasound alone. The scan measures volume and assesses texture, nodules and vascularity.
Ultrasound shows superficial structures such as the thyroid, lymph nodes and soft tissues in high detail. It defines lesion size, composition and relation to surrounding tissues.
Common symptoms and signs
- Dimensions of both lobes and isthmus
- Homogeneous or heterogeneous texture
- Number and TI-RADS features of nodules
- Cervical lymph nodes when indicated
Diagnosis and the role of ultrasound
The radiologist evaluates shape, margins, contents, calcification and blood flow. TI-RADS features are used for thyroid nodules; lymph nodes are assessed by shape, cortex and fatty hilum.
- Size, shape and exact location
- Solid, cystic or mixed composition
- Margins and relation to adjacent tissue
- Doppler flow and risk features
Ultrasound findings must be interpreted together with symptoms, examination and, when needed, laboratory or other imaging results. An image alone should not be used for self-diagnosis or self-treatment.
Treatment and next steps
Correlate with TSH and other tests; an endocrinologist determines treatment or biopsy need. Depending on findings, observation, laboratory testing, specialist review or needle biopsy may be advised. Size alone does not determine management.
Management is individual and depends on age, symptoms, imaging findings, other health conditions and pregnancy plans. Medication or a procedure should be selected with the appropriate clinician.
When is urgent care needed?
- Difficulty breathing or swallowing
- A rapidly enlarging, painful or hard mass
- High fever, marked skin redness or severe swelling
