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]. 1992, 185: 125-130.
