A 65-year-old man with a history of metastatic squa-mous cell carcinoma of the tongue underwent a percutaneous kyphoplasty at an outside hospital for a painful T9 metastatic compression fracture. Immediately after the procedure, the patient developed saddle anesthesia and progressive bilateral lower extremity numbness and weakness. He was then transferred to our hospital for further care. Computed tomography and magnetic resonance imaging revealed kyphoplasty cement within the T9 vertebral body (Fig. 1) with retropulsion of tumor mass into the ventral spinal canal (Fig. 2). The patient underwent emergent posterolateral decompression with T9 verte-brectomy, anterior reconstruction T8-T10, and posterior instrumented spinal fusion (Fig. 3). Histopathological examination confirmed the diagnosis of metastatic squa-mous cell carcinoma. Postoperatively, the patient regained full strength and sensation along with the ability to ambulate.
