Study DesignRetrospective chart review and review of the recent literature.ObjectivesTo present our experience, over an 8-year period, with aggressive microsurgical resection of intramedullary spinal tumors in adults focusing on histology, microsurgical techniques, short-term neurological outcomes, complication avoidance and dorsal column dysfunction(More)
OBJECT Human bone marrow stromal cells (hMSCs) constitute a potential source of pluripotent stem cells. In the present study, hMSCs were transplanted into an area of spinal cord contusion in nude rats to determine their survival, differentiation, potential for neuroprotection, and influence on axonal growth and functional recovery. METHODS Twenty-nine(More)
Intraventricular neoplasms of the third ventricle represent a small minority of intracranial tumors. Furthermore, few cases of solitary, third ventricular glioblastoma multiforme were reported in the literature. The authors report a case of a fifty-nine year olf man who presented with progressive gait disturbance, disorientation, diffuse headache, and(More)
Leiomyosarcoma is a rare malignant smooth-muscle tumor that rarely metastasizes to bone. It is extremely uncommon for osseous metastasis to be the initial presentation of leiomyosarcoma or to be the initial manifestation of recurrence in patients with a history of leiomyosarcoma. The authors have treated four cases of metastatic leiomyosarcoma with the(More)
Appropriate differentiation between epidermoid-dermoid and arachnoid cysts is important for patient management. MRI has had limitations in differentiating these two types of cysts, especially in the region of the spinal cord. To evaluate the role of diffusion-weighted (DW) MRI for differentiation between spinal arachnoid and epidermoid-dermoid cysts. Four(More)
BACKGROUND Controversy exists as to the best posterior operative procedure to treat multilevel compressive cervical spondylotic myelopathy. OBJECTIVE To determine clinical, radiological, and patient satisfaction outcomes between expansile cervical laminoplasty (ECL) and cervical laminectomy and fusion (CLF). METHODS We performed a prospective,(More)
Twenty-five patients underwent an expansive cervical laminoplasty for nontraumatic cervical spondylosis with myelopathy during the period from June 1990 to November 1994, and all had a minimum of 18 months of follow-up review. The open-door laminoplasty procedure presently reported consisted of the same approach evaluated by Hirabayashi in 1977, except that(More)
Since virtually no trials have evaluated the effectiveness of temozolomide (TMZ) in the treatment of spinal cord (SC) glioblastoma multiforme (GBM), we conducted a systematic review to evaluate its efficacy. Primary SC GBM is rare. Its management remains unclear, even though treatment guidelines have been established since 2005 for its cranial counterpart.(More)
BACKGROUND AND IMPORTANCE Cavernous malformations of the cranial nerves are exceedingly rare. The classic radiographic appearance of cavernous malformations may not be obvious when located in a cranial nerve. CLINICAL PRESENTATION We present 2 cases of acute oculomotor paresis caused by cavernous malformations of the oculomotor nerve that were mistaken(More)
