Single-point de-identified axial radiographic dataset (LS+SI+pelvis) demonstrating a mixed but predominantly degenerative pattern with superimposed thoracolumbar/upper-lumbar DISH-pattern flowing ossification. Dominant burden is at L1-L2 and L2-L3, with severe disc loss, marked endplate remodeling, scoliosis, mild non-erosive SI change, and low inflammatory structural signal.
This case demonstrates how structured axial imaging can clarify a mixed structural phenotype that might otherwise be oversimplified in routine referral language. The radiographic pattern is not an erosive axial inflammatory arthropathy. Instead, the dominant signal is a combined ossific-degenerative spine phenotype: thoracolumbar/upper-lumbar DISH-pattern flowing ossification, severe upper-lumbar degenerative disc disease centered at L1-L2 and L2-L3, scoliosis, mild chronic non-erosive sacroiliac change, and only mild accompanying hip/pelvic degenerative-enthesopathic findings.
For clinicians, the value of this case is the explicit separation of major pattern components rather than collapsing them into a vague “arthritis” label. The report makes the axial burden distribution, DISH-pattern morphology, sacroiliac non-inflammatory appearance, and absence of convincing erosive sacroiliitis or syndesmophytic disease directly readable in one framework.
For research and pharma use, this case is useful because it preserves phenotype clarity. The addendum explicitly classifies the study as a mixed axial ossific-degenerative phenotype with high mechanical-degenerative dominance, high ossific enthesopathic signature, and low inflammatory structural signature, while also stating that longitudinal delta metrics are not computable because this is a single-timepoint dataset without matched priors. That makes the case human-readable, analysis-ready, and audit-ready without overstating what radiographs alone can prove.
