Cavernous sinus hemangiomas (CSHs) are rare vascular tumors. Stereotactic radiosurgery is an effective treatment for small CSHs. The optimal treatment for giant CSHs is controversial. This study reports advantages of a complete intradural transcavernous approach in total resection of CSHs. ⋯ Surgical total resection is the primary and reasonable choice for giant CSHs. Microsurgical resection of giant CSHs through a completely intradural transcavernous approach is an alternative treatment option for giant CSHs.

To compare the outcome of anterior cervical decompression and fusion (ACDF) and posterior laminoplasty (LAMP) for treating 4-level cervical spondylotic myelopathy (CSM). ⋯ Both ACDF and LAMP were effective in the treatment of multilevel CSM. Compared with LAMP, ACDF is less invasive and may be more suitable for elderly patients with poor tolerance of surgery.

Computer-assisted three-dimensional navigation often guides spinal instrumentation. Optical topographic imaging (OTI) offers comparable accuracy and significantly faster registration relative to current navigation systems in open posterior thoracolumbar exposures. We validate the usefulness and accuracy of OTI in minimally invasive spinal approaches. ⋯ OTI is a novel navigation technique previously validated for open posterior exposures and in this study has comparable accuracy for mini-open minimally invasive surgery exposures. The likelihood of successful registration is affected more by the geometry of the exposure than by its size.

Percutaneous Doxycycline Foam Injections, A Novel Treatment Method for Vertebral Aneurysmal Bone Cysts.
Aneurysmal bone cysts (ABCs) are among the most aggressive benign bone tumors, often occurring in both long bones and the spine. Treatment remains controversial as recurrence rates continue to be high. Treatment options include curettage with or without bone grafting, arterial embolization, en block resection with or without instrumentation or arthrodesis, radiation, and intralesional drug injections (steroids, calcitonin, doxycycline). ⋯ At the 1-year follow up appointment, all symptoms had been resolved. Repeat computed tomography and magnetic resonance imaging demonstrated that the ABC had nearly filled in completely with new bone. Our case demonstrates successful use of this percutaneous, less invasive method in the management of vertebral ABCs.

Meningiomas are the second commonest intracranial tumors in many places worldwide. They are rare in the pediatric age group, however, and most studies have been able to document only a few patients. Meningiomas in pediatric patients have also been shown to behave differently from those in the adult population. This study was done to examine histologic types of meningiomas seen in pediatric patients from a predominantly African population using the 2016 World Health Organization (WHO) grading system for intracranial tumors. ⋯ Our study showed the rarity of meningiomas in the study population, and there was a predominance of basally located tumors.
