Between June 2009 and August 2009, there were 1,534 consecutive patients with 1,632 thyroid nodules who underwent US-guided fine needle aspiration (US-FNA) on focal thyroid nodules larger than 5mm in our institution (a referral center) in Korea. Marked hypoechogenicity, microlobulated or irregular margins, microcalcifications, and taller than wide shape were considered suspicious malignant features of thyroid nodules on US (Figure2) [13]. Homogenous is the opposite and would mean the gland is uniform in size. Thus, the aim of this study was to evaluate the influence of underlying thyroid echogenicity on diagnosis of thyroid malignancies using US. The .gov means its official.

Patients with Graves disease were defined as positive for TBII. Cookies policy. These nodules are widespread, but most are benign. BMC Cancer 13, 550 (2013). Eur Arch Otorhinolaryngol. 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]. The authors declare that they have no competing interests. Thyroid. eCollection 2021. Chaudhary V & Bano S. Thyroid Ultrasound.
