“…Determining the underlying pathologic characteristics of primary thyroid lymphoma could lead to a reasonably specific sonographic category for this disease. Recently, sonographic findings of primary thyroid lym-phoma were correlated with pathologic findings in studies by Orita et al 3 and Nam et al 4 Both studies showed that the hypoechoic areas of primary thyroid lymphoma were consistent with lymphoepithelial lesions containing neoplastic cells, whereas echogenic structures within or around the lesions were consistent with fibrotic tissue. Therefore, primary thyroid lymphoma lesions should histopathologically include lymphoma cells and reactive connective tissue.…”

“…An early diagnosis of primary thyroid lymphoma can lead to timely treatment and a favorable prognosis 2 . However, there are few reports about the sonographic features of primary thyroid lymphoma, and the results have had some disparity 3 – 9 . In addition, its Doppler flow pattern was not known.…”

“…However, sialolithiasis shows stones Satomi Omotehara 6 with acoustic shadows in the dilated ducts. Malignant lymphomas, especially mucosa-associated lymphoid tissue lymphoma (MALT lymphoma), show hypoechoic areas with rough or dense linear echogenic strands and a lobulated shape with a markedly hypoechoic internal echo texture in the thyroid and salivary glands [17,18], making them especially difficult to distinguish from IgG4-SS.…”

PurposeWe evaluated the sonographic findings of immunoglobulin G4-related sclerosing sialadenitis (IgG4-SS). MethodsNineteen patients with IgG4-SS and 12 healthy volunteers (controls) were enrolled. The following sonographic features were evaluated: 1) enlargement of the submandibular gland by measurement of the longitudinal diameter and thickness; 2) the contour texture of the submandibular gland (smooth or rough); 3) the internal echo texture, categorized into three sonographic patterns (homogeneous, multiple hypoechoic nodule, and diffuse hypoechoic); and 4) quantitative color Doppler signaling. ResultsThe longitudinal diameter and the thickness (mean ± SD) of the submandibular gland were significantly greater in patients than in controls (p=0.005 and p<0.001, respectively). Contour roughness was seen in 62.9% and 8.3% of patients and controls (p<0.001), respectively.Homogeneous echo textures alone were seen in controls, whereas multiple hypoechoic nodule patterns were seen in 60% of patients, and diffuse hypoechoic patterns were seen in 40%. Color Doppler signaling (mean ± SD) was significantly higher in patients as compared with controls (p<0.001). ConclusionPatients could be distinguished from healthy volunteers using four distinctive sonographic findings, suggesting that ultrasonography would be a useful diagnostic tool for IgG4-SS.

“…Some studies suggested that sonographic findings of PTL were correlated with pathologic findings. Orita et al (33) and Nam et al (29) indicated that the hypoechoic areas of PTL were consistent with lymphoepithelial lesions containing neoplastic cells, whereas echogenic structures within or around the lesions were consistent with fibrotic tissue and normal thyroid tissue. Ota (9) reported a destructive linear pattern which might suggest the transformation of MALT lymphoma into a high-grade malignant lymphoma.…”

Background: Although primary thyroid lymphoma (PTL) and anaplastic thyroid carcinoma (ATC) both account for a rare portion of the morbidity of all thyroid malignancies, the therapeutic methods and prognosis for these two diseases are different. The purpose of this study was to investigate the sonographic characteristics of PTL and ATC and to compare the sonographic findings of PTL and ATC. Methods:The study included 42 patients with histopathologically proven PTL (n=27) and ATC (n=15). The Clinical characteristics and sonographic findings were retrospectively reviewed and compared between the two groups.Results: The mean age of patients with ATC was not significantly different from that in patients with PTL (P=0.601). The female-to-male ratio of patients with ATC was significantly lower than that of patients with PTL (P=0.029). Both PTL and ATC commonly present as a relatively large, solid mass on sonography with compressive symptoms, in which hoarseness was seen more frequently in ATC group (66.7%) than in PTL group (14.8%) (P=0.001). There is no significant difference in thyroid size, nodular size, margin, shape, echo texture, echogenicity, cystic change, vascularity and local invasion on sonography between ATC and PTL groups. Echogenic strands, markedly hypoechoic and enhanced posterior echo were seen more frequently in PTL group (92.6%, 92.6%, and 85.2%, respectively) than those in ATC group (6.7%, 60.0%, and 33.3%, respectively) (P<0.05), and calcification was seen more frequently in ATC group (80.0%) than in PTL group (0%) (P<0.001). Three ultrasound patterns were observed for PTL including diffuse type (25.9%), nodular type (48.2%) and mixed type (25.9%), while all ATC cases presented with nodular type (100.0%). AssociatedHashimoto's thyroiditis occurred more frequently in PTL group (59.3%) than in ATC group (20.0%) (P=0.023). Conclusions: Certain sonographic features as a markedly hypoechogenicity, the presence of an enhanced posterior echo and linear echogenic strands, lack of calcification and associated Hashimoto's thyroiditis were valuable for distinguishing PTL from ATC. In contrast, heterogeneous echogenicity, uncircumscribed margin, irregular shape, and vascular pattern were not specific features for differential diagnosis.
