A condition that increases the size of your thyroid is called a goiter. Thyromegaly is more commonly known as a goiter.

A total of 1,373 patients who underwent US-guided fine needle aspiration of 1,449 thyroid nodules from June 2009 to August 2009 were included. A biopsy of a thyroid nodule can determine if a nodule is cancerous. Its estimated that roughly one-third of the global population has a low iodine intake. Hypoechoic nodules are darker than the surrounding thyroid tissue, which suggests that the nodules are solid rather than fluid-filled. Heterogeneous echogenicity of the thyroid parenchyma does not influence the detection of multi-focality in papillary thyroid carcinoma on preoperative ultrasound staging. The ATA also note that solid hypoechoic thyroid nodules have a higher chance of becoming cancerous compared to cystic or fluid-filled lesions. Although we believe that false-negative and false-positive results were negligible in our institution [36], the results of our study may be affected. A hypoechoic thyroid nodule is a type of thyroid nodule that appears dark on an ultrasound scan and typically indicates a solid mass rather than a fluid-filled cyst. CAS After US, each US feature was recorded by the radiologists who performed the US on provided result sheets including the underlying echogenicity of the thyroid gland on US.

In benign thyroid nodules, we could still more often find microlobulated or irregular margin on US in nodules with heterogeneous thyroid echogenicity than in those with homogenous thyroid echogenicity (P=0.007). Heterogeneous echogenicity of the underlying thyroid parenchyma: how does this affect the analysis of a thyroid nodule? and transmitted securely. doi: 10.1067/msy.2099.101431. For example, cystic or fluid-filled thyroid nodules are often benign, which means they are noncancerous. Thyroid glands with heterogeneous echogenicity showed significantly lower specificity, PPV, and accuracy compared to thyroid glands with homogeneous echogenicity, 76.3% to 83.7%, 48.7% to 60.9%, and 77.6% to 84.4%, respectively (P=0.009, 0.02 and 0.005, respectively).
