淋巴瘤是由淋巴细胞异常增殖引起的恶性肿瘤,约占所有恶性肿瘤的8%,分为霍奇金病(Hodgkin disease,HD)和非霍奇金淋巴瘤(non-Hodgkin lymphoma,NHL)。25%~40%的淋巴瘤,特别是NHL,可发生于淋巴结或淋巴组织以外,称为结外淋巴瘤[1]。结外淋巴瘤常见受累部位为胃肠道、头颈部、眼眶、中枢神经系统、肺、骨和皮肤等全身组织及脏器。泌尿系统结外淋巴瘤相对罕见,其早期诊断、及时治疗对患者具有重要意义[2]。熟知泌尿系统结外淋巴瘤的临床及影像学表现对临床、影像及病理医师均极为重要。本文对泌尿系统原发性结外淋巴瘤的临床及影像学表现作一综述。

摘要: 淋巴瘤是临床最常见的恶性肿瘤之一,但原发性结外淋巴瘤并不常见,来源于泌尿系统的淋巴瘤则更为罕见。泌尿系统原发性结外淋巴瘤中,肾是最常见的受累部位,其次为膀胱,输尿管淋巴瘤最为罕见,其常见症状有腹痛、腹部肿块、肾功能不足、血尿和排尿困难等,熟知其影像学表现对临床诊断及治疗均很重要。

Abstract: Lymphoma is one of the most common malignant tumors in clinic. But primary extranodal lymphomas is not frequently encountered clinically especially for the lymphomas which stem from urinary system. Kidney was the most common affecting area, followed by bladder and ureter. Palpable masses, abdominal pain, renal insufficiency, hematuria and difficult urination are the main clinical symptoms of primary extranodal lymphoma of the urinary system. Familiarity with the imaging features will be helpful to the accurate diagnosis and therapy. -
