| Abstract: | The value of post-myelographic spinal computer tomography (CT) was evaluated in cancer patients with spinal metastases causing complete myelographic block. In 22 out of 25 lumbar myelographies (88%) showing complete blockade, sufficient contrast medium had leaked proximally to allow determination of the cranial limit of the metastasis on the CT-scan. It is concluded that the post-myelographic spinal CT can replace a supplementary cervical myelography in the majority of patients with epidural metastasis, causing a complete myelographic block. |
