The plain films and myelographic findings in 92 cases of spinal cord tumors including 31 metastatic tumors are presented. The neoplasm in the majority of the cases were in the thoracic region, 64%; the other sites being lumbar, 22%, sacral, 7%, and cervical, 7%. Ten percent were in the intramedullary, 28% in the intradural extramedullary, 4% in both intradural and extradrual and 58% in extradural in location. Thirty seven percent in intraspinal benign tumors reveal erosive change in bones and 83% in malignant tumors caused radiologically visible none destruction and soft tissue change. Characteristic finding of intramedullary tumor is symmetric enlargement of cord shadow with narrowing of lateral gutters. Contrast column shows beading along the lateral border due to filling of root pouch. Sharply defined concave defect in association with slight widening and lateral beaking of oil column at tumor site are characteristic of intradual tumor. Usually the cord shadow is displaced ontralaterally. Extradural lesion produce obstruction with ill defined dentate border, smooth tapering or irregular narrowing of oil column, which is usually narrowed at tumor site. The cord shadow is normal or slightly displaced. An evaluation of the myelographic changes in intramedullary, intradural extramedullary and exradural tumors indicates that it is usually possible to make correct location of intraspinal tumors with reasonable accuracy.
