Is it possible for "myelomalacia" read on an mri to be an ms plaque? what is the difference between such a finding being read as myelomalacia vs. tra

Myelomalacia: is not a specific disease but can result from a variety of factors. Literally "softening of the cord", it is focal decreased size or shrinkage of the cord accompanied by signal abnormality. It is caused by damage or insult to the cord such as from trauma, hemorrhage, vascular insufficiency, etc... In a relatively small percentage of MS cases(usually long standing), it can be present

See a neurosurgeon: Myelomalacia indicates a possible old injury. That could be from MS if someone has that diagnosis. More common cause is from a disc herniation/bulge. You should see a neurosurgeon if this is a possibility. If there is no active compression of the spinal cord from a disc and there is a history of MS then seeing your neurologist would be the best evaluation.
