title: Role of computed tomography in patients with "sciatica".
abstract: The computed tomography (CT) findings in 10 patients who presented with lumbosacral radicular symptoms are reported. The CT scans were performed after the more commonly used radiologic studies, including plain films and myelography, had failed to completely define the nature or extent of the underlying disease process. The final diagnoses were metastatic neoplasm to the spine and soft tissue in six cases, primary neoplasm of the sacrum or soft tissue in three cases, and tuberculous osteomyelitis and abscess in one case. The limitations and potential complications of the various radiologic examinations are discussed, and the potential value of CT in selected patients with lumbosacral neuropathy is presented.
