Neuroradiological diagnosis of intraspinal tumors in children

In the diagnosis of spinal and intraspinal space-occupying processes great importance attaches to radiologic plain film diagnosis, including special projections and tomography. Using refined evaluation methods, direct and indirect signs of tumors can be demonstrated in 30-50% of cases. Of decisive importance is the myelographic examination. It permits the determination of the exact localization and the size of a tumor. Contrast studies frequently allow an identification of the tumor type. Spinal arteriography and phlebography, on the other hand, are of secondary importance in the diagnosis of tumors of both spinal canal and spinal cord. In patients with bone infiltration they accomplish a valuable contribution to determine whether this expansion is directed towards the epidural space or the soft tissue structures of the back.
