The case of a 70-year-old woman with progressive renal cell carcinoma (RCC) metastatic invasion of a L3 vertebral hemangioma treated by dual percutaneous radiofrequency ablation (RFA) and vertebroplasty is reported. The patient was surgically treated for RCC in 2001. Chemotherapy and immunotherapy were introduced in 2013 for ovarian, bladder and cerebral metastatic disease. An asymptomatic L3 benign hemangioma was noticed at this time. One-year CT and MRI follow-up studies demonstrated a nodular isolated soft tissue lesion involving the anterior edge of the hemangioma. Percutaneous treatment consisted of a L3 vertebral body unipedicular approach to perform a biopsy, RFA with a navigational bipolar RFA device and vertebroplasty using high viscosity cement. Histopathological examination confirmed metastasis of RCC. The 5-month spinal MRI and CT examinations demonstrated complete disappearance of the tumor.
报告了一例70岁女性，患有进行性肾细胞癌（RCC），其转移侵袭至L3椎体血管瘤，采用双经皮射频消融（RFA）和椎体成形术进行治疗。该患者于2001年接受了RCC手术治疗。2013年针对卵巢、膀胱和脑转移疾病采用了化疗和免疫治疗。此时发现了一个无症状的L3良性血管瘤。为期一年的CT和MRI随访研究显示，有一个结节状孤立软组织病变累及血管瘤前缘。经皮治疗包括采用L3椎体单椎弓根入路进行活检，使用导航双极RFA设备进行RFA以及使用高粘度骨水泥进行椎体成形术。组织病理学检查证实为RCC转移。5个月后的脊柱MRI和CT检查显示肿瘤完全消失。
