The CT studies of 29 patients with renal or perirenal lymphoma were retrospectively reviewed. Four patterns of disease were identified. Seventeen of 29 patients (59%) had bilateral renal masses. Only seven of these patients had associated enlarged retroperitoneal lymph nodes. Eight patients (28%) had single renal or perirenal lesions adjacent to or contiguous with bulky retroperitoneal lymphadenopathy. Three patients had infiltration of the perirenal space without significant renal parenchymal involvement, and one patient had a solitary renal mass. No patients in this series had diffuse involvement of the kidney without a focal mass. Renal involvement with lymphoma should be considered in any patient who develops multiple homogeneous solid renal or perirenal masses, even in the absence of other retroperitoneal disease.
对29例肾或肾周淋巴瘤患者的CT研究进行了回顾性分析。确定了四种疾病模式。29例患者中有17例（59%）有双侧肾肿块。这些患者中只有7例伴有腹膜后淋巴结肿大。8例患者（28%）有单个肾或肾周病变，与肿大的腹膜后淋巴结相邻或连续。3例患者有肾周间隙浸润，但无明显肾实质受累，1例患者有孤立性肾肿块。该系列中没有患者出现无局灶性肿块的肾脏弥漫性受累。对于任何出现多个均匀实性肾或肾周肿块的患者，即使没有其他腹膜后疾病，也应考虑肾淋巴瘤受累。
