A broad spectrum of benign renal neoplasms in adults shows characteristic ontogeny, histology, and tumor biology. Benign renal tumors are classified into renal cell tumors, metanephric tumors, mesenchymal tumors, and mixed epithelial and mesenchymal tumors. Select benign tumors show characteristic anatomic distribution and imaging features. However, because of overlapping of findings between benign and malignant renal tumors, histologic evaluation may be required to establish a definitive diagnosis. Accurate preoperative characterization facilitates optimal patient management.
We attempt to provide a comprehensive, contemporary review of benign renal neoplasms that occur in adults, focusing on cross-sectional imaging characteristics.
成人多种良性肾肿瘤具有独特的起源、组织学及肿瘤生物学特征。良性肾肿瘤分为肾细胞肿瘤、后肾肿瘤、间叶性肿瘤以及上皮和间叶混合性肿瘤。部分良性肿瘤具有特征性的解剖分布及影像学表现。然而，由于良性和恶性肾肿瘤的表现存在重叠，可能需要进行组织学评估以明确诊断。准确的术前特征描述有助于优化患者管理。
我们试图对成人发生的良性肾肿瘤进行全面、当代的综述，重点关注横断面成像特征。
