【摘要】：目的探讨原发甲状腺淋巴瘤(PTL)的超声表现及病理特征。方法回顾性分析28例经穿刺或手术病理证实的PTL患者的声像图表现,对病变的超声分型、形态特点、边界、回声及周围组织侵犯情况进行分析,并分析上述超声表现与其病理特征的关系。结果 28例PTL病例均为非霍奇金淋巴瘤,其中弥漫大B细胞淋巴瘤19例,结外边缘带B细胞淋巴瘤/低度恶性黏膜相关组织淋巴瘤6例,结外边缘带B细胞淋巴瘤伴大细胞转化3例。7例合并桥本甲状腺炎。超声示甲状腺弥漫性肿大,累及单侧或双侧,多呈不均匀极低回声,可有条索状强回声,后方回声增强,可伴数目不等的低回声结节,边界欠清,易侵犯颈部淋巴结,还可累及周围软组织、压迫气管。结论充分认识不同病理类型的PTL超声表现特点、结合病史及临床资料,有助于提高PTL的超声诊断准确率。
[Abstract]:Objective to investigate the primary thyroid lymphoma (PTL) ultrasound manifestations and pathological features. Methods Retrospective analysis of 28 cases of sonographic biopsy or surgical pathology in patients with PTL, the lesions by type, morphological characteristics, boundary, echo analysis and surrounding tissue invasion, and analyzed the relationship between the ultrasound findings and pathological features. The results of 28 PTL cases were non Hodgkin lymphoma, including 19 cases of diffuse large B cell lymphoma, extranodal marginal zone B cell lymphoma / 6 cases of low-grade mucosa associated lymphoid tissue lymphoma, extranodal marginal zone B cell lymphoma with large cell transformation of 3 cases of.7 patients with Hashimoto thyroiditis showed diffuse thyroid ultrasound. Swelling, unilateral or bilateral involvement is very uneven, low echo, a streak of strong echo, rear echo enhancement, hypoechoic nodules with unequal numbers, boundary less clear, easy invasion of cervical lymph node Conclusion we can also involve the surrounding soft tissue and compress the trachea. Conclusion we should fully understand the PTL features of different pathological types, and combine the history and clinical data, which is helpful to improve the accuracy of PTL ultrasound diagnosis.

【正文快照】： 原发性甲状腺淋巴瘤(primary thyroid lympho-ma,PTL)是一种原发于甲状腺的罕见疾病,仅占甲状腺恶性肿瘤的0.6%~5%[1]。由于PTL发病率低及对其认识不足,PTL常被误诊为桥本甲状腺炎(Hashimoto's thyroiditis,HT)或甲状腺癌。PTL的治疗与其他结外淋巴瘤类似,但不同于甲状腺癌。
