Abstract
Patients [22] with mass or destructive lesions at different levels of the spine underwent closed needle biopsy guided by computed tomography (CT). Of the 22 specimens obtained, 8 were sufficient for a histologic diagnosis. In 1, normal bone tissue obtained was not consistent with the clinical and radiographic picture, resulting in a false negative diagnosis. Except for 1 patient who developed transient quadriparesis that resolved spontaneously within 2 days, no bleeding complications or neurologic deficits attributable to the procedure were noted. Closed needle biopsy of spinal lesions under CT guidance is advocated as a safe and convenient technique for all levels of the spine. Modifications of the needle used and more experience will be necessary to increase the yield of positive results.
