During the past five years a total of 75 tumors involving the spinal canal have been studied by myelography at Montefiore Hospital. Twenty (27 per cent) of these proved to be metastatic cancer and 6 (8 per cent) lymphoma, a total of 26 (35 per cent). The relatively high incidence of malignant tumors in this series can be explained by the fact that the institution from which this report emanates has a large, active neoplastic service, and patients are maintained under surveillance for the duration of their illness. The experience of others indicates a much lower frequency of spinal metastatic tumors. Sachs (15) found 20 (9 per cent) metastatic carcinomas and 28 (12 per cent) sarcomas (no further specification as to type) in a total of 234 spinal tumors. Elsberg (9) encountered only 14 (5 per cent) metastatic tumors in 267 cases. Wood (20) indicates the incidence to be 10 per cent. However, he makes no mention of lymphoma. Lymphomas of the spinal canal are less frequently encountered than would be implied b...
