The role of ultrasound in distinguishing between IgG4‑positive Hashimoto’s thyroiditis and primary thyroid lymphoma: a pilot study
IgG4-positive Hashimoto’s thyroiditis (IgG4-HT) is an aggressive HT subtype that may be misdiagnosed as primary thyroid lymphoma (PTL) due to overlapping clinical and imaging features. This study aimed to evaluate the utility of ultrasound for non-invasive differentiation between IgG4-HT and PTL. Data from...
