Intracerebral hemorrhage (ICH) is a subtype of stoke that may cause significant morbidity and mortality. Brain injury due to ICH initially occurs within the first few hours as a result of mass effect due to hematoma formation. However, there is increasing interest in the mechanisms of secondary brain injury as many patients continue to deteriorate(More)
OBJECT There are a variety of treatment options for the management of vestibular schwannomas (VSs), including microsurgical resection, radiotherapy, and observation. Although the choice of treatment is dependent on various patient factors, physician bias has been shown to significantly affect treatment choice for VS. In this study the authors describe the(More)
OBJECT Rhabdoid glioblastoma (GB) is an exceedingly rare tumor in which some of the tumor cells possess rhabdoid features such as eccentric nuclei, abundant eosinophilic cytoplasm, and pseudopapillary formations. These tumors are exceptionally aggressive, and leptomeningeal dissemination is common. In the 9 previously reported cases, the longest survival(More)
The rosette-forming glioneuronal tumor (RGNT) of the fourth ventricle is a recently described, rare, and distinct tumor of the glioneuronal family. The presentation, natural history, and treatment response of these tumors has been unclear as there are no significant series of a sizeable population with long-term follow-up. We report a comprehensive analysis(More)
OBJECTIVES Spinal cord stimulation (SCS) is a well-established modality for the treatment of chronic pain, and can utilize percutaneous or paddle leads. While percutaneous leads are less invasive, they have been shown to have higher lead migration rates. In this study, we compared the long-term outcomes and health-care costs associated with paddle and(More)
OBJECTIVE The prognosis of elderly patients with glioblastoma (GBM) is universally poor. Currently, few studies have examined postoperative outcomes and the effects of various modern therapies such as bevacizumab on survival in this patient population. In this study, the authors evaluated the effects of various factors on overall survival in a cohort of(More)
STUDY DESIGN Retrospective cohort analysis. OBJECTIVE To examine the effect of resection on survival and neurological outcome in a modern cohort of patients with spinal cord astrocytomas and identify prognostic factors for survival. SUMMARY OF BACKGROUND DATA There are currently no clear treatment guidelines for the management of spinal cord(More)
Adult brainstem gliomas (BSG) are uncommon tumors that constitute only 2% of all brain tumors. Due to its rare occurrence in the elderly (60 years and older), there is no literature discussing the natural history, prognosis, and best treatment strategy for malignant BSG in this population to our knowledge. We report seven elderly patients with malignant BSG(More)
BACKGROUND Surgical site infections increase the incidence of morbidity and mortality as well as health-care expenses. The cost of care increases threefold to fourfold as a consequence of surgical site infection after spinal surgery. The aim of the present study was to determine the role of subcutaneous fat thickness in the development of surgical site(More)
STUDY DESIGN Retrospective cohort analysis. OBJECTIVE To evaluate the neurological outcomes after resection of intramedullary, intradural extramedullary, and extradural hemangiomas. SUMMARY OF BACKGROUND DATA Spinal hemangiomas most commonly arise in the vertebral bodies and are typically asymptomatic. Uncommonly, hemangiomas may cause significant(More)
