Case:A 45-year-old woman with severe back pain underwent percutaneous curettage and balloon kyphoplasty (BKP) of a lesion believed to be aneurysmal bone cyst. Three months after BKP, local recurrence was observed, and the histological diagnosis was revised to malignant tumor. Thus, we performed a total en bloc spondylectomy, and the L3 vertebral body was resected. She was reconstructed by titanium expandable cage, rod, and pedicle screws. We observed viable tumor cells and foreign body reaction adjacent to the polymethylmethacrylate cement, carrying no bone necrosis.Conclusions:The long-term durability and safety of BKP for metastatic spine disease should be further clarified.
