Objective To present a previously unreported patient with recurrent spinal metastasis from subcutaneous sacrococcygeal ependymoma who was followed for 16 years. Methods A 50-year-old man who had T9 metastasis from subcutaneous sacrococcygeal ependymoma underwent piecemeal total T9 excision at a local hospital. He was referred to our institute because of weakness in both legs and bowel-bladder d...

Although metastatic spread of prostate carcinoma to the spinal column is common, involvement of the spinal intradural extramedullary compartment is exceedingly rare. Presentation of intradural metastases tends to be late in the course of the disease, is frequently associated with cerebral metastasis and the role of surgery is limited to palliation and prevention of neurological deterioration. H...

This article describes a patient with multiple metastases from renal cell carcinoma who survived and maintained an ambulatory status for 15 years with no recurrence in the spine after en bloc resection of solitary spinal metastasis. Skeletal metastasis from renal cell carcinoma is common, second only to lung metastasis. Surgery plays an important role in the treatment of the metastasis because ...

BACKGROUND AND PURPOSE Systematic investigations of the distinguishing imaging features between spinal hyperplastic hematopoietic bone marrow and bone metastasis have not been reported, to our knowledge. The purpose of this study was to determine the distinguishing imaging features of the 2 entities. MATERIALS AND METHODS We retrospectively reviewed the radiologic images of 8 consecutive male...

With the progress of image-guided localization, body immobilization system, and computerized delivery of intensity-modulated radiation delivery, it became possible to perform spine radiosurgery. The next question is how to translate the high technology treatment to the clinical application. Clinical trials have been performed to demonstrate the feasibility of spine radiosurgery and efficacy of ...

Neurological deterioration sometimes follows removal of cerebro-spinal fluid by lumbar puncture below a spinal block caused by a tumour. Experience has shown that similar impaction of a spinal intradural tumour may occur following the draining of hydrocephalus. We have used the term "upward spinal coning " to describe this and report four cases in which impaction of an intradural metastasis occ...

OBJECTIVE To evaluate the risk factors and prognosis of surgery for spinal metastasis. METHODS A retrospective analysis was performed in 63 patients with spinal metastasis who underwent surgical treatment between June 1992 and June 2002. Forty-one patients underwent anterior en-bloc or partial resection, decompression and reconstruction with internal fixation of the spine. Laminectomy and dec...
