Study Notes
Neck Mass
- Hashimoto's disease is the most common form of thyroiditis. The typical clinical presentation is a painful, diffusely enlarged gland in a young or middle-aged woman. The sonographic appearance is enlarged, and the parenchymal is often hypoechoic, and frequently identified by thickened fibrous strands.
- Goiter is the most common cause of diffuse thyroid enlargement. Goiter is caused by inadequate iodine ingestion and is not a significant problem in the United States.
- Thyroid nodules are very common. In the United States, 4% to 8% of adults are estimated to have thyroid nodules, 10% to 41% are visible with palpation, and 50% are discovered at autopsy.
- The risk that a thyroid nodule is malignant increases with age. Thyroid cancer is more common in patients 20 years or older than 60 years. A history of neck radiation or a family history of thyroid cancer also increases the risk. Most nodules that are encountered clinically are benign but not clinically significant.
- A nodule with almost always contain mostly cystic changes, loss ofogenicity, round shape.
- Color Doppler imaging of the normal thyroid structure shows minimal flow, which usually is located near the poles of the gland.
- Benign nodules are either are underlying thyroid tissue, or follicular adenomas. Adenomas are less common than follicular carcinomas. Benign nodules have no vascular or capsular invasion.
