Lymphoma of the thyroid is a rare condition, classically occurring in elderly caucasian women, presenting as a rapidly enlarging, symptomatic mass. Almost all examples are due to non-Hodgkin's lymphoma, and the lesion is commonly superimposed on pre-existing Hashimoto's thyroiditis. Prognosis is best if the disease is diagnosed early and while confined to the thyroid region, there being a favourable response to radiotherapy alone. Unfortunately, lymphoma is rarely considered in the differential diagnosis of thyroid masses, often leading to unnecessary, excessive surgery. Ultrasonography of five patients was analysed to determine if any common diagnostic features were present. All had a similar pattern, with a large, circumscribed, solid hypoechoic mass. Although nonspecific, this appearance, with awareness of a rapidly growing mass, should alert the radiologist and attending clinician to the possibility of lymphoma.
甲状腺淋巴瘤是一种罕见疾病，典型地发生于老年白种女性，表现为迅速增大的有症状肿块。几乎所有病例都由非霍奇金淋巴瘤引起，且病变通常叠加于先前存在的桥本甲状腺炎之上。如果疾病早期诊断且局限于甲状腺区域，预后最佳，单独放疗就有良好反应。不幸的是，甲状腺肿块的鉴别诊断中很少考虑淋巴瘤，这常导致不必要的过度手术。分析了5例患者的超声检查结果以确定是否存在任何共同的诊断特征。所有患者都有相似的表现，即一个大的、边界清晰的实性低回声肿块。虽然这种表现不具特异性，但结合迅速生长的肿块，应提醒放射科医生和主治医生注意淋巴瘤的可能性。
