What is echogenicity of thyroid?
The echogenicity refers to the brightness of a thyroid nodule relative to the rest of the thyroid tissue. Hypoechoic nodules are darker than the surrounding thyroid tissue, which suggests that the nodules are solid rather than fluid-filled.
What is heterogeneous echogenicity of the thyroid?
Heterogeneous echogenicity of the thyroid gland is a non-specific finding and is associated with conditions diffusely affecting the thyroid gland. These include: Hashimoto thyroiditis. Graves disease.
What does hypoechoic thyroid nodule mean?
A hypoechoic nodule, sometimes called a hypoechoic lesion, on the thyroid is a mass that appears darker on the ultrasound than the surrounding tissue. This often indicates that a nodule is full of solid, rather than liquid, components.
What do thyroid ultrasound results mean?
A thyroid ultrasound is usually done when physical exam shows any of these findings: You have a growth on your thyroid gland, called a thyroid nodule. The thyroid feels big or irregular, called a goiter. You have abnormal lymph nodes near your thyroid.
Should I worry about thyroid nodule?
The vast majority — more than 95% — of thyroid nodules are benign (noncancerous). If concern arises about the possibility of cancer, the doctor may simply recommend monitoring the nodule over time to see if it grows. Ultrasound can help evaluate a thyroid nodule and determine the need for biopsy.
Is a heterogeneous thyroid normal?
Heterogeneous echogenicity of the thyroid gland has been associated with diffuse thyroid disease and benign and malignant nodules can coexist with diffuse thyroid disease. Underlying heterogeneous echogenicity might make it difficult to differentiate between benign and malignant nodules on US.
What are the symptoms of heterogeneous thyroid?
The extra thyroxine can cause symptoms of an overproduction of thyroid hormones (hyperthyroidism), such as:
- Unexplained weight loss.
- Increased sweating.
- Tremor.
- Nervousness.
- Rapid or irregular heartbeat.
Is hypoechoic or hyperechoic better?
Hyperechoic tissues generate a greater echo usually displaying as lighter colors during ultrasound imaging. Hypoechoic – Refers to structures that create weaker echoes such as a fluid. Tissues with lower echogenicity are usually represented as darker colors on ultrasound.
Can Hashimoto’s be diagnosed by ultrasound?
Hashimoto’s thyroiditis is a type of autoimmune thyroid disease with an increasing prevalence in past decades. Its diagnosisis mostly based on ultrasonography. Ultrasonography is a useful and essential tool to make this diagnosis based on the characteristics of the disease.
