Hemangioblastomas are benign vascular neoplasms that may be associated with von Hippel-Lindau disease. They are more common in men, with a mean age of 36 years, and rarely affect the supratentorial region and, when present in this topography, do not have meningeal impairment. Diagnosis by the radiologic and histopathologic study is difficult, since they are rare and, therefore, forgotten diagnosis, besides they are differential diagnoses with other supratentorial neoplasms. ⋯ Definitive treatment for these lesions is surgical resection. Physicians should be aware that supratentorial meningeal hemangioblastomas can be developed in a patient without von Hippel-Lindau disease and regular follow-up is mandatory.

Three-level lumbar en bloc spondylectomy with 3D-printed vertebrae reconstruction for recurrent giant cell tumor.
Primary malignancies involving the mobile spine often require total en bloc spondylectomy with complex mechanical reconstruction, which can be augmented with novel application of the 3-dimensional (3D)-printing technique. ⋯ To our knowledge, this is the first reported case of multilevel lumbar TES for GCT reconstructed using a 3D-printed vertebrae. Although TES-specifically in the lumbosacral spine-remains challenging due to its unique anatomy and increased risk of neurologic insult, it is an effective option for curative management of GCTs.

The concept of enhanced recovery after surgery (ERAS) spread to different surgical specialties to minimize surgical stress response and to reduce length of hospital stay (LOS) and cost. Recently, several studies have reported experience with the ERAS program for spine surgery. The aim of this study is to introduce the establishment and implementation of the ERAS pathway for minimally invasive surgery (MIS) transforaminal lumbar interbody fusion (TLIF). ⋯ Our ERAS program tailored for MIS-TLIF is able to reduce LOS and cost with minimal complications. The ERAS pathway expedites recovery in patients undergoing lumbar spine fusion.

The aims of this study were to evaluate the risk factors for muscle injury in patients undergoing posterior lumbar spinal surgery and the clearance of postoperative biochemical changes following lumbar fusion and secondarily to evaluate the timing for monitoring postoperative biochemical serum levels and potential clinical correlation. ⋯ The risk of RML increases with prolonged and invasive surgery with higher bleeding potential. Knowing the clearance of postoperative biochemical changes permits a standardized strategy with measurements in precise intervals, thereby avoiding unnecessary costs. The clinical significance is still undetermined.

Primary central nervous system (pCNS) melanoma is an extremely rare malignant tumor. We explored the incidence, outcomes, and predictors of pCNS melanoma. ⋯ The overall age-adjusted incidence rate of pCNS melanoma is 0.52 per 10,000,000 person-years. Age ≤19 years and intracranial tumor location are independent risk factors of low survival rate, whereas gross total resection is associated with better survival rate.
