Non-Hodgkin's lymphoma are neoplasms derived from T cells and B cells and their precursors in the lymphoid system with higher susceptibility in involvement of extra-nodal sites. Predominant ureteric involvement is an unusual presentation. We present a case of diffuse large B-cell lymphoma with secondary involvement of ureter who had symptoms of urinary tract infection in absence of positive urine culture, non-responsive to broad spectrum antibiotics and masquerading pyogenic infection leading to pyelonephritis with ureteritis. Radiological examination revealed mass like soft tissue thickening of ureter extending from renal pelvis throughout the length of ureter. FNAC as well as biopsy from the periureteric thickening revealed lymphomatous involvement of ureter. The following case report provides insight on differentials and varied symptoms of lymphomatous involvement of ureter.
非霍奇金淋巴瘤是起源于淋巴系统中T细胞、B细胞及其前体细胞的肿瘤，结外部位受累的易感性较高。输尿管为主的受累是一种不寻常的表现。我们报告一例弥漫性大B细胞淋巴瘤继发输尿管受累的病例，该患者有尿路感染症状，但尿培养阴性，对广谱抗生素无反应，伪装成化脓性感染，导致肾盂肾炎伴输尿管炎。影像学检查显示输尿管有肿块样软组织增厚，从肾盂延伸至输尿管全长。细针穿刺抽吸活检以及输尿管周围增厚组织活检均显示输尿管有淋巴瘤累及。以下病例报告提供了输尿管淋巴瘤累及的鉴别诊断及多样症状的见解。
