Ultrasound of primary thyroid non-Hodgkin's lymphoma

ObjectiveThe aim of this study was to review the high-frequency ultrasonography findings of primary thyroid non-Hodgkin's lymphoma (PT-NHL).MethodsData of 39 patients treated for PT-NHL and 48 patients as controls were retrospectively reviewed.ResultsThe mean age of patients, Hashimoto's thyroiditis, marked hypoechogenicity of the lesion, asymmetrical enlargement of the thyroid, cervical lymph node enlargement, enhancement of posterior echoes, and linear echogenic septations were all more statistically significantly different in the PT-NHL group than in the control group.ConclusionUltrasonographic characteristics predictive of PT-NHL are marked hypoechogenicity in the lesion and asymmetrical enlargement of the thyroid gland.
