Infiltrative renal malignancies are a subset of renal masses that are morphologically characterized by a poorly defined interface with the renal parenchyma. Infiltrative renal malignancies are less common but more aggressive than more typical renal malignancies and carry an overall worse prognosis. Although an infiltrative renal process often represents a malignant neoplasm, infiltrative masses include a wide spectrum of diseases including primary renal cortical, medullary, and pelvic tumors; lymphoproliferative processes; metastases; and various infectious, inflammatory, immune-mediated, and vascular mimics. The imaging features of these masses are often nonspecific, but with the appropriate history, laboratory results, and clinical context, the radiologist can help narrow the diagnosis and guide further treatment.

浸润性肾恶性肿瘤是肾肿块的一个子集，其形态学特征是与肾实质的边界不清。浸润性肾恶性肿瘤比更典型的肾恶性肿瘤少见，但更具侵袭性，总体预后更差。尽管浸润性肾病变通常代表恶性肿瘤，但浸润性肿块包括广泛的疾病，包括原发性肾皮质、髓质和盆腔肿瘤；淋巴增殖性病变；转移瘤；以及各种感染性、炎症性、免疫介导性和血管性模仿病变。这些肿块的影像学特征通常不具有特异性，但结合适当的病史、实验室检查结果和临床背景，放射科医生可以帮助缩小诊断范围并指导进一步治疗。RSNA，2021年。
