The relative effectiveness of plain computed tomography (CT), metrizamide CT, conventional myelography, and magnetic resonance (MR) imaging was compared for the examination of cystic spinal cord lesions. Intramedullary cavities in 18 patients were demonstrated by MR imaging: cavities were uncomplicated in 13 patients, associated with spinal tumors in two, and studied after occipital craniectomy...

Primary gliosarcoma (GS) in the spinal cord is extremely rare. To our knowledge, there are only two cases reported in the literature. The clinical feature, treatment, and prognosis for this rare entity have been uncertain. In this paper, we present a unique case of histopathologically proven primary intramedullary spinal GS without intracranial involvement. A 46-year-old male presented with a 3...

Early diagnosis and prompt initiation of adequate treatment are essential for clinical outcome in ISCA. We report a case in which DWI provided a more specific diagnosis than conventional MR imaging and allowed differentiation of a ring-enhancing lesion from intramedullary tumor. Diagnosis was proved by PCR from CSF (Streptococcus intermedius). Adequate antibiotic treatment was immediately initi...

Intraoperative sonography was performed in 20 children in order to localize intramedullary spinal cord tumors. It provided excellent visualization of the extent and consistency of the tumor before surgical opening of the dura mater. The sonographic findings were used in selecting the site and extent of myelotomy. Intraoperative sonography proved to be a valuable adjunct to spinal cord surgery.

Background. The objective of our study was to evaluate the stabilization of reconstructed long bones after metastatic tumor resection and defect filling with polymethyl methacrylate (PMMA) or bone allograft. Material and methods. We studied a group of 107 patients who underwent surgery between 1996 and 2004 (55 females and 46 males). A primary neoplasmatic focus was found after histopathologica...
