and not complete exclusion. Despite the evolution in the understanding of the pathophysiology, diagnostic tools, and treatment modalities, the rarity and gradual progression of spinal vascular diseases still makes them difficult to diagnose and treat properly. We reviewed our 20-year treatment records to evaluate their clinical characteristics and analyze the treatment outcomes. Methods Patient Selection Under the approval of our institutional review board (Seoul National University Hospital and Seoul National University Bundang Hospital), we

SEDAVFs are rare, few studies have sought to systematically investigate the clinical presentation, imaging characteristics, and treatment outcomes. In fact, studies of these lesions are limited to very small case series or case reports. We reviewed a consecutive series of SEDAVFs diagnosed and treated at our institution and report on clinical presentation, functional status, and treatment outcomes. Methods Patient Population Following institutional review board approval, we reviewed a consecutive series of angiographically confirmed SEDAVFs diagnosed and treated at our

more aggressive treatment modalities such as resection or Gamma Knife surgery (GKS) can be used to prevent symptomatic vp-AVM or to treat intracranial hemorrhage (ICH) associated with a vp-AVM. Nevertheless, poorly localized abnormal lesions due to the absence of a definite nidus and enlarged feeding arteries as well as limited information on long-term treatment outcomes after GKS can make it difficult to select the appropriate treatment modality. The aim of this study was to report our experience with the long-term treatment outcomes of vp-AVMs as well as review the

, neuroimaging findings, histopathological results, and treatment outcomes of 7 pediatric patients with AB who had been surgically treated at our institution. Methods Study Population A retrospective review of a database of all intracranial ABs surgically treated at our institution between November 1994 and January 2019 was performed. Seven patients with AB were included in this study. The median patient age was 13 years (range 7–18 years). Five patients were female and 2 were male. The median clinical follow-up duration was 96 months (range 48–189 months). The

We compare clinical presentations, angioarchitecture, and treatment outcomes of neonates and infants with DAVFs presenting in the first year of life with those of children presenting later in life (between the ages of 1 and 18 years). Finally, we compare the outcomes of children with DAVFs with other pediatric intracranial arteriovenous shunts

(STEs) and cortical ependymomas (CEs) are relatively infrequent. About 45 cases of STE have been reported, the majority as case reports. 11 Resection is the first-choice treatment for STE; however, there has been open controversy within the neuro-oncology community regarding the optimal postoperative treatment for adults with STE. 19 , 28 In this report, we retrospectively analyzed the clinical characteristics, neuroimaging findings, pathological features, and treatment outcomes of 14 patients with STE who had been surgically treated in our department between January

predictive value for survival and treatment outcome. Clinical Material and Methods Patient Population In a prospective study consecutive patients with brain metastases from different radioresistant primary cancers underwent treatment between December 1998 and October 2005 at the Gamma Knife Center in Krefeld, Germany. Neurological deficits present on the day of GKS were defined as presenting symptoms and neurological symptoms documented at the last follow-up examination were defined as the neurological outcome. The KPS score rather than the number of metastases was used as

This paper focuses on surgery and radiation therapy; a companion article will appraise developments and opportunities with systemic therapies. Methods A PubMed literature search
