Giant cell tumor of the sacrum is usually silent in initial stages and not diagnosed until achieving a large size. Intralesional curettage of the tumor has lower risk of neurological damage but is with high recurrence rate. Zoledronic acid-loaded cement was demonstrated to have cytotoxic effect on the cell line of giant cell tumor. This study evaluate if zoledronic acid-loaded bone cement would reduce the recurrence rate of sacral giant cell tumor after intralesional curettage. ⋯ We suggested that placement of zoledronic acid-loaded bone cement was an effective adjuvant therapy for sacral giant cell tumor following intralesional curettage.

To investigate the clinical outcomes and imaging features of malignant peripheral nerve sheath tumors (MPNSTs) presenting as spinal dumbbell tumors. ⋯ There is little clinical information relating to spinal dumbbell MPNSTs. We propose that the following imaging features are suggestive of spinal dumbbell MPNSTs: maximal diameter>5 cm, irregularly lobulated shape, boundary indistinguishable from surrounding tissues, and osteolytic bone destruction.

Renal cell carcinoma (RCC) is an aggressive disease that metastasizes to the spine often requiring surgery. However, selecting the appropriate surgical intervention can be challenging. The Tokuhashi scoring system can be used to predict survival and inform the surgical strategy. We set out to determine the Tokuhashi score for patients with RCC spine metastases and compare expected and observed survival. ⋯ RCC is an aggressive disease with short life expectancy when metastatic to the spine. However, patients with low systemic disease burden and solitary spinal metastases can have long survival and benefit from excisional surgery. Tokuhashi score can be useful in selecting surgical intervention in patients with RCC spinal metastases, and may be more relevant than in other cancers with spinal metastases.

Vertebral hemangiomas (VHs) are the most common form of benign tumors in the spine. The aim of this research was to study the prevalence of VHs in the human population, their distribution along the spine and their location in the vertebral body. ⋯ The reported prevalence of VHs is dependent on the demographic structure of the population studied, the size of the VHs and the method used to identify them. Overall, the phenomenon is more frequent than usually reported. VHs may appear at all vertebral levels and in all areas of the vertebral body.

Estimating the survival time of patients with spinal metastases based on pre-treatment parameters is important for the best choice of therapy. Following two previous studies, this sequel analyzes possible changes in the impact of various parameters and scoring systems and includes a comparison to the previous dataset for the purpose to find the most predictive parameters and scores for this patient group. ⋯ The Bauer modified score has shown consistent impact on predicting the remaining survival in patients with spinal metastases and is simultaneously simple in clinical use.
