These include: Thyroid goiter: The diagnosis and treatment of thyroid goiters. Although US is a powerful modality for differentiating malignancy from benign focal thyroid nodules [13, 15, 34], some studies have speculated that it might be difficult to detect malignant nodules in patients with HT on US because the heterogeneous hypoechogenicity and micronodulation seen in HT are somewhat similar to features seen in malignant thyroid nodules [2, 12]. Table2 shows the diagnostic performance of US in the differential diagnosis of thyroid nodules, comparing the two groups with and without underlying heterogeneous echogenicity of the thyroid parenchyma on US. In particular, the association between HT and papillary thyroid carcinoma (PTC) has been reported in many studies [5, 79]. WebA poorly defined margin that is not infiltrative, is often used to describe a nodule that appears to merge into the surrounding thyroid without discrete borders.

Of the 1,449 nodules included, 317 (21.9%) showed underlying heterogeneous echogenicity of the thyroid parenchyma on US. Doctors typically evaluate thyroid nodules using an ultrasound examination, or sonogram. Besides these considerations, there are no published reports on this topic: Does underlying thyroid parenchyma echogenicity affect the analysis of a thyroid nodule? The US-FNAs were performed either on the thyroid nodule with suspicious US features or on the largest thyroid nodule if no suspicious US features were detected.
