Kidney neoplasms are common diseases with varying prognoses depending on the subtype of the tumor. The most common solid lesion of the kidney is renal cell carcinoma, and the treatment is typically surgical removal. With increasing use of cross-sectional imaging in the last two decades, the detection of renal lesions has significantly increased, especially in asymptomatic patients who are scanned for other reasons. In this article, we present the imaging findings of rare solid benign primary kidney neoplasms including renal leiomyoma, reninoma, carcinoid tumor, metanephric adenoma, solitary fibrous tumor of the kidney, lipomatous hemangiopericytoma of the kidney, renal schwannoma, inflammatory myofibroblastic tumor of the kidney, extramedullary hematopoiesis in the kidney, and extranodal renal Rosai-Dorfman disease. Accurate preoperative or prebiopsy diagnoses of these lesions are unusual; however, informed radiologists may sometimes be able to favorably change the patient management and treatment.
肾肿瘤是常见疾病，其预后因肿瘤亚型而异。肾脏最常见的实性病变是肾细胞癌，治疗通常是手术切除。在过去二十年中，随着横断面成像技术的使用增加，肾脏病变的检出率显著提高，尤其是在因其他原因进行扫描的无症状患者中。在本文中，我们展示了罕见的实性良性原发性肾肿瘤的影像学表现，包括肾平滑肌瘤、肾素瘤、类癌肿瘤、后肾腺瘤、肾孤立性纤维瘤、肾脂肪血管瘤样血管外皮细胞瘤、肾神经鞘瘤、肾炎性肌成纤维细胞瘤、肾髓外造血以及肾结外Rosai-Dorfman病。对这些病变进行准确的术前或活检前诊断并不常见；然而，经验丰富的放射科医生有时可能能够有利地改变患者的管理和治疗。
