Abstract
Aberrant nerve fibers within the spinal cord are described in 9 cases with varying diagnoses. The origin of these fibers in 6 of the cases was seen to be in the cell bodies of the posterior spinal ganglia while the origin in the other 3 cases is suggested to be in the anterior horn neurons. The nerve fiber bundles are similar to traumatic neuromata. An important observation common to all cases was that mesodermal connective tissue, not central nervous tissue, surrounded the abnormal fibers. The most probable explanation for the origin of these aberrant nerve fibers is that they arise from the proliferation of severed axons.
