SUBACUTE COMBINED DEGENERATION OF THE SPINAL-CORD - MRI DETECTION OF PREFERENTIAL INVOLVEMENT OF THE POSTERIOR COLUMNS IN A CHILD

Subacute combined degeneration of the spinal cord (vitamin B-12-deficient myelopathy) is a neurologic disorder manifesting progressive symptoms of paresthesia and spastic paralysis. As shown by pathology, it initially involves the posterior columns of the thoracic cord. We present a case of vitamin B,, deficiency with preferential posterior column involvement of the thoracic cord in a child, Theoretically, this should be the earliest, most reversible stage of the disease, making recognition of this MRI pattern of critical importance.
