What is a transitional vertebra with partial lumberization of what will be termed S1 on the right side? It is noted as a normal anatomic variant but is associated with low back pain according to the Dr. who read the MRI. He also says comparison with prior studies will be helpful in accurately numbering the vertebra. Also, a rudimentary S1-2 disc space is present. Otherwise unremarkable MRI of the sacrum.
