OBJECT Intraspinal hemangioblastomas are relatively uncommon benign tumors. The surgical strategies remain controversial, and the risk factors with regard to clinical outcome are unclear. The purpose of this study was to analyze the clinical characteristics, imaging findings, surgical strategies, and functional outcomes associated with intraspinal(More)
Intramedullary spinal cord gangliogliomas are rare tumors composed of glial components and ganglion cells. These gangliogliomas are generally considered as slow-growing tumors, corresponding histologically to WHO grade I or II. There are few reports of large case series of intramedullary spinal cord gangliogliomas from a single center. We retrospectively(More)
Spinal cord subependymomas are very rare. Most studies on spinal cord subependymomas have been case reports with literature reviews. This study presented a surgical series of 13 patients with histologically proven spinal cord subependymomas. Their clinical data, radiological findings, operative records, and follow-up outcomes were reviewed. There were 5(More)
OBJECT Intramedullary schwannomas are exceedingly rare. Most previous studies are case reports with an associated literature review. The aim of this study was to discuss the clinical features and the outcomes of microsurgery for these rare lesions. METHODS The authors retrospectively reviewed the data of twenty patients with intramedullary schwannomas.(More)
Intramedullary spinal schwannomas are rare benign spinal cord tumors and are easily misdiagnosed because of the imaging characteristics shared with intramedullary glioma. Correct preoperative definitive diagnosis is essential for treatment and prognosis. To improve the preoperative diagnostic strategy, clinical and imaging data of seven patients with(More)
OBJECT Neuropathic arthropathy (Charcot joint) caused by syringomyelia is rare and commonly misdiagnosed. Few cases have been reported by neurosurgeons. The aims of this study were to analyze the clinical and imaging presentations of neuropathic arthropathy and to discuss the effect of surgical management of the primary neurological deficits on neuropathic(More)
A remarkable preservation of sensorimotor function is observed in patients with refractory epilepsy who were treated by hemispherectomy. Cortical regions in the remaining hemisphere or contralateral subcortical region contribute to the residual sensorimotor function. Somatosensory evoked field (SEF) is used to investigate the residual sensory function in(More)
Primary spinal peripheral primitive neuroectodermal tumors (pPNETs) are extremely rare entities that predominantly occur in children and young adults. Few studies have reported more than three cases. There are no current optimum treatment strategies due to the paucity of data. Here, we present 13 patients (nine females and four males) with primary(More)
OBJECT Intramedullary neurenteric cysts (NECs) are exceedingly rare lesions and have been previously reported in case reports. The aim of this study was to determine the clinical manifestations, radiological features, and long-term prognosis of patients with such lesions. METHODS The authors retrospectively reviewed the records of 13 patients with an(More)
Spinal intradural malignant peripheral nerve sheath tumors (MPNSTs) in children are extremely rare, with only five reported cases in the literature. A 9-year-old female with neurofibromatosis type 2 (NF-2) presented with right hip pain and severe weakness of bilateral legs for 3 months. Magnetic resonance (MR) imaging revealed multiple intradural masses at(More)
