Clear cell sarcoma of the kidney is the most frequently misdiagnosed renal tumor in children. We report the case of a 6-year-old boy with clear cell sarcoma of the kidney with an unusual presentation, including a primary tumor of the left kidney with metastasis in the homolateral psoas muscle. The renal tumor was revealed by abdominal mass without hematuria. In a review of the literature. Clear cell sarcoma of the kidney is most commonly associated with bone and lung metastases. Muscular metastasis at initial diagnosis has not previously been reported. This case represents an unusual metastatic pattern of clear cell sarcoma of the kidney. This also illustrates clear cell sarcoma of the kidney's ability to metastasize to other sites including the muscular. These tumors present a diagnostic challenge for the radiologist who should be aware of this entity to differentiate it from other renal tumors which are more frequent at this age. We aim to report the clinical, radiological features, and pathological presentation of this entity.
肾透明细胞肉瘤是儿童中最常被误诊的肾脏肿瘤。我们报告了一例6岁患有肾透明细胞肉瘤的男孩，其表现不寻常，包括左肾原发性肿瘤并伴有同侧腰大肌转移。肾肿瘤通过腹部肿块发现，无血尿。在文献回顾中，肾透明细胞肉瘤最常与骨和肺转移相关。此前尚未报道过初始诊断时出现肌肉转移的情况。该病例代表了肾透明细胞肉瘤一种不寻常的转移模式。这也说明了肾透明细胞肉瘤转移至包括肌肉在内的其他部位的能力。这些肿瘤给放射科医生带来了诊断挑战，放射科医生应了解这一实体，以便将其与该年龄段更常见的其他肾脏肿瘤区分开来。我们旨在报告该实体的临床、放射学特征及病理表现。
