title: [Diagnostic significance of percutaneous needle biopsy in metastatic neoplasms of the spine].
abstract: A retrospective review of percutaneous needle biopsy due to the vertebral metastatic neoplasms performed in 92 patients treated from 1975 to 1992 at Department of Neurosurgery, K. Marcinkowski University of Medical Sciences. Thoracic biopsies constituted 45 per cent, lumbar-32 per cent, cervical-18 per cent and sacral ones 5 per cent of all procedures. An accurate diagnosis was made in 70 per cent of all cases. The highest accuracy rate was noted in lesions compromising the entire vertebral body (84 per cent) and posterior elements of the vertebrae (89 per cent). Tomographic X-rays, CT and MRI were helpful in visualization of concomitant paravertebral mass. In these cases accuracy rate of the biopsy was 82 per cent. The technique of percutaneous biopsy and histological results were also discussed.
