Abstract Objective: To evaluate imaging findings with ultrasound and CT imaging techniques in primary thyroid lymphoma(PTL). Methods: 39 cases of histopathologically proven PTL were gathered for this study. We retrospectively reviewed the sonographic and CT findings of PTL. Results: The mean age of the patients was 65 years old. In sonography, there were 10 cases of diffuse PTL, of which 8 showed enlargement of the thyroid gland and enhancement of post acoustic, 9 showed hypoechogenicity, and 2 showed calcification in lesions; The cases of nodular PTL were 29, of which 19 showed hypoechogenecity and post acoustic enhancement of thyroid, 26 showed reduced echo of lesions, and 3 showed calcification in lesions. 26 of 39 PTL patients had cervical lymph node enlargement. In axial plain CT scans, there were 4 cases of diffuse PTL, 2 cases showed low density, and 1 case showed calcification in lesions; The cases of nodular PTL were 17, 14 cases showed low density, and 2 cases showed calcification in lesion. The above 21 cases showed the same classification types in sonographic and CT findings, of which 8 cases showed cervical lymphadenopathy and 4 cases showed upper mediastinal lymphadenopathy. Of the 14 patients who underwent contrast-enhanced axial CT images, 10 were moderately or mildly enhanced and 9 were homogeneous enhanced. Conclusion: The ultrasonography and CT findings of patients with PTL have corresponding imaging characteristics, and these two can be complementary which help to diagnose PTL.
