For the selection of treatment in patients with spinal bone metastases (SBM), survival estimation plays a crucial role to avoid over- and under-treatment. To aid clinicians in this difficult task, several prediction models have been developed, consisting of many different risk factors. The aim of this systematic review was to identify prognostic factors that are associated with survival in patients with SBM to support development of predictive models. ⋯ Prognostication for patients with SBM should be based on an accurate primary tumor classification, combined with a performance score. The benefit of adding other prognostic factors is doubtful.

Review Case Reports
Surgical complications of extraspinal tumors in the cervical spine: a report of 110 cases and literature review.
To assess the safety of surgical intervention for extraspinal tumors in the cervical spine. ⋯ Surgery for cervical spine tumor could improve the quality of life, though it might be accompanied with high morbidity and mortality. It is a highly demanding procedure; however, it can be performed to an acceptable degree of safety.

We report an uncommon case of paraspinal hibernoma with a T12-L1 foraminal extension and discuss the potential differential diagnoses of paraspinal adipocytic tumors. ⋯ Based on the Grand Round case and relevant literature, we discuss a rare case of paraspinal hibernoma with a foraminal component and no recurrence at 3-year follow-up.

Spinal solitary fibrous tumor/hemangiopericytoma (SFT/HPC), a rare mesenchymal tumor that arises from pericytes of Zimmerman, comprises only 0.08% of all primary bone tumors and 0.1% of primary malignant bone tumor and rarely occurs in the spine. We attempt to correlate the clinical factors and different treatment options with the recurrence rate and overall survival of SFT/HPC over time. ⋯ Spinal osseous SFT/HPC is a challenging clinical entity given its high local recurrence rate. Surgical management plays a crucial role in the whole treatment of spinal SFT/HPCs and total excision, especially TES, should be strived for whenever possible. Postoperative radiotherapy is recommended to lower the recurrent rate. This study also confirms that pathology grade III is an adverse prognostic factor for spinal osseous SFT/HPCs.

To assess paraspinal neurogenic tumors with diffusion-weighted MR imaging. ⋯ Diffusion-weighted MR imaging is imaging parameter that can be used for differentiation of benign from malignant paraspinal neurogenic tumors.
