Review Case Reports
Spinal hemangiopericytoma: an institutional experience and review of literature.
Hemangiopericytoma is a rare tumor of CNS with potential for recurrence and widespread metastasis, even outside CNS with even rare involvement of spinal cord. This case series presents five patients to evaluate the clinical presentation, radiological features, management, pathology and outcome of spinal hemangiopericytomas. ⋯ Spinal hemangiopericytoma is a rare tumor. Strong clinical suspicion is required to diagnose it pre-operatively. Gross total resection is the goal and radiotherapy should be given in case of residual tumor or high-grade tumors.

Traumatic spinal cord injuries (TSCI) are among the most devastating conditions in developed and developing countries, which can be prevented. The situation of TSCI around the world is not well understood which complicates the preventive policy decision making in fight against TSCI. This study was aimed to gather the available information about incidence of TSCI around the world. ⋯ Data of epidemiologic information in TSCI are available for 41 countries of the world, which are mostly European and high-income countries. Researches and efforts should be made to gather information in developing and low-income countries to plan appropriate cost-effective preventive strategies in fight against TSCI.

Review Case Reports
C1-C2 pigmented villonodular synovitis and clear cell carcinoma: unexpected presentation of a rare disease and a review of the literature.
Pigmented Villonodular synovitis (PVNS) is a rare vertebral pathology--around 50 reports, only 3 concerning C1-C2 location. ⋯ A large differential diagnosis should be made when the typical findings for metastatic disease are absent precluding the iatrogenic consequences of empirical treatments based on clinical diagnosis with no histopathological support.

Multicenter Study
Surgical treatment of sacral chordoma: prognostic variables for local recurrence and overall survival.
Sacral chordomas (SC) are rare, locally invasive, malignant neoplasms. Despite surgical resection and adjuvant therapies, local recurrence (LR) is common and overall survival (OS) is poor. The objective of this study was to identify prognostic factors that have an impact on the local recurrence-free survival (LRFS) and OS of patients with SC. ⋯ This study identified two predictive variables for LRFS (previous tumor surgery and type of surgical resection) and two for OS (age and impaired motor function) in surgically treated SC patients. Our results indicate that en bloc resection reduces LR but does not influence OS. However, this was likely due to short follow-up (3.2 years).
