Metastatic renal osteosarcoma is a rare entity. We report a case of a 52-year-old male postright nephrectomy status presented to us with metastatic renal osteosarcoma. 18-fluorine- fluorodeoxyglucose (F-FDG) avid lesions were seen in the right renal bed with extension to adjacent hepatic parenchyma. The patient exhibited a favorable response to 6 cycles of carboplatin and doxorubicin with no FDG avid lesions in the postchemotherapy follow-up scan. On 6-month follow-up scan, scan findings reveal a recurrent lesion at the renal bed region infiltrating psoas muscle and liver metastatic lesion. This case highlights the use of F-FDG positron emission tomography/computed tomography in metastatic recurrent extraskeletal osteosarcoma.
转移性肾骨肉瘤是一种罕见的疾病。我们报告一例52岁男性患者，在右肾切除术后出现转移性肾骨肉瘤。在右肾床可见18氟-氟脱氧葡萄糖（F-FDG）摄取增高的病灶，并延伸至相邻的肝实质。该患者对6个周期的卡铂和阿霉素治疗反应良好，化疗后随访扫描未见FDG摄取增高的病灶。在6个月的随访扫描中，扫描结果显示肾床区域出现复发病灶，侵犯腰大肌和肝脏转移病灶。该病例突出了F-FDG正电子发射断层扫描/计算机断层扫描在转移性复发性骨外骨肉瘤中的应用。
