Expanding lesions in or about the spinal canal may compress the spinal cord and impair or destroy its functions by producing within it minimal, moderate or marked interference with the circulation.
CASES PRODUCING MILD INTERFERENCE WITH THE CIRCULATION
Expanding lesions that directly compress the spinal cord without producing interference with the circulation are relatively rare. In cases in which very mild interference with the circulation occurs, it plays an insignificant rôle in the causation of the signs and symptoms. In such cases the neurologic manifestations are primarily due to pressure causing disturbances in the conductivity of the fiber tracts. The histopathologic changes are correspondingly very slight.Six cases of this type were found in our series. For the sake of brevity, only one will be described in detail, and the remaining five will be summarized briefly.
