ABSTRACT
INTRODUCTION:
Bone metastases confined to the posterior elements of the spine are rarely treated, as there exist no established radical surgical treatment options for this area. Herein, we present a case report of and technical note on a patient who underwent radical resection for a metastatic tumor in the thoracic spinous process. CASE PRESENTATION A 34-year-old male presented with a nasopharyngeal carcinoma with a solitary metastatic focus in the spinous process of the 10th thoracic vertebra. Imaging revealed that the tumor was confined to the spinous process and the surrounding soft tissues. No tumor was noted in the pedicles, vertebral body, and cortical bone on the ventral side of the lamina, as well as within the spinal canal. As treatment for this solitary metastatic lesion, we decided to perform radical resection with sufficient margins that would include the involved spinous process and all surrounding soft tissues exhibiting evidence of tumor infiltration. The posterior elements of the 9th-11th vertebrae, multifidus muscles, and skin were widely resected en bloc using a T-saw. The posterior elements of the spinal column were resected at the level of pedicles without full visualization of the involved dural sac. The tumor-infiltrated soft tissues surrounding the T10 vertebral spinous process were excised without full visualization of the tumor. Adjuvant therapy was not administered postoperatively. During the second year of follow-up, no signs of recurrence or metastasis were noted.DISCUSSION:
Our proposed technique allows wide resection of a solitary focus of metastasis in the posterior elements of the spine.
