Please help, I have Crohn’s Disease and a 15+ history of lower back pain improved with movement. I recently saw a Rheumatologist and I had a Mri of SI joints and full spine my results were:
There is partial lumbarization of the S1 with enlarged left transverse process which shows Pseudoarthrosis with the main sacral body (Castellvi classification Type IIA)
Otherwise lumbar vertebral bodies show normal height and signal intensity. There is small lipomatous area noted within the L4. No evidence of any enthesitis.
Mild left lateral L2-L3, L3-L4 disc protrusion slightly contacting the L2 and L3 nerve roots in the extraforaminal regions. No significant compression. Normal appearances of the facet joints. Spinal canal diameter is capacious.
The Rheumatologist said, no evidence of spondyloarthritis, do you guys agree?
Many thanks in advance
