Abstract:
Objective:To evaluate the sonographic characteristics of primary lymphoma of the thyroid gland and to analyze histo-pathologic findings and other imaging features to improve the diagnostic accuracy of this disease. Methods: We retrospectively re-viewed the records of 20 patients with histologically proven primary lymphoma of the thyroid gland. The clinical, pathologic, sono-graphic, CT, and MRI features were analyzed. Results:Histology revealed non-Hodgkin lymphoma in 20 patients. Ultrasound revealed lateral thyroid lobe disease in 12 cases and the presence of unilateral masses in 8 cases. The main features seen were diffusely enlarged thyroid gland. The lateral or unilateral thyroid lobe was with hypoechoic masses intermingled with echogenic structures. A total of 16 cases showed enlarged lymph nodes, 5 cases showed invasion of trachea, and 1 case involved the trachea and esophagus. Conclusion:Primary lymphoma of the thyroid gland usually presents with clinical and sonographic findings mimicking a carcinoma or benign tu-mor. If clinical features revealed rapidly enlarging neck masses and sonographic characteristics represented by malignant features of Hashimoto thyroiditis, then we should consider lymphoma. However, the final diagnosis depends on histopathology.
