Signs and symptoms of involvement of the central nervous system in lymphoblastic disease are not unusual but actual invasion of the brain and spinal cord is extremely rare. Symptoms referable to the spinal cord in patients who have these lesions most often arise as the result of pressure on the cord occurring after collapse of an involved vertebra.

We have seen a number of cases in which there appeared to be primary involvement of the spinal epidural space without evidence of tumor elsewhere. These cases form the basis of this report.
Search of the records at the Mayo Clinic revealed 39 cases in which the primary symptoms of tumor of the spinal cord were due
