Overview
Neck ultrasound may be performed to detect papillary thyroid cancer.
Ultrasound
- Ultrasound imaging is useful in the diagnosis and management of thyroid cancer. It is used for:[1][2]
- Evaluation of thyroid nodule characteristics
- Determination of nodule location during fine needle aspiration study
- Assessment of adjacent lymph node for the purpose of staging the cancer
- Post-surgical surveillance for early detection of tumor recurrence and/or nodal metastatic disease
- In summary, ultrasound imaging findings suggestive of malignant thyroid nodule include:
- Microcalcification
- Peripheral, coarse calcification
- Solid, hypoechoic nodule
- Locally invaded nodule (more commonly seen in anaplastic thyroid cancer and primary thyroid lymphoma)
- High anteroposterior/width ratio
- Irregular nodular margin
- Adjacent suspicious lymph node with a size greater than 2 cm
- Presence of posterior acoustic shadowing
- Additionally, ultrasound imaging has been observed to be useful in the diagnosis of non-palpable lymph node metastasis when used preoperatively.
- Key ultrasound Findings in papillary thyroid cancer include:
- Hypoechoic nodule in the majority of cases
- Microclacifications that are seen as tiny punctate echogenic foci within the nodule (most common finding)
- Posterior acoustic shadowing from the edges of the nodule
