RheumaView™ · Case Study · Longitudinal
A conventional radiology report beside a RheumaView™ structured longitudinal report — one peripheral dataset, two timepoints, read for structural stability rather than dramatic damage.
This is a low-damage early case: there is no erosive transformation and no interval progression, so it is not a “dramatic findings” showcase. Its value is the opposite — showing how a structured report frames stability over time, keeps subtle degenerative/mechanical background separate from inflammatory interpretation, and flags an honest data limitation (the follow-up hand series is richer than baseline).

The visualized osseous structures are intact, with no acute fracture or dislocation. Bony mineralization appears within normal limits. The carpal and metacarpophalangeal joint spaces are grossly maintained. No aggressive osseous lesion is identified. The overlying soft tissues are unremarkable.
No acute fracture or dislocation is seen. There is mild bilateral hallux valgus. No aggressive osseous lesion is identified. The visualized joint spaces are grossly preserved and the ankle mortises appear maintained. The remainder of the examination is unremarkable.
1. No significant acute osseous abnormality of the hands, wrists, feet or ankles.
2. Mild bilateral hallux valgus.
No acute osseous abnormality. Alignment preserved bilaterally. Bone mineralization maintained without convincing periarticular osteopenia. MCP, PIP and DIP joint spaces preserved bilaterally without convincing inflammatory joint-space narrowing. Radiocarpal, intercarpal and visualized carpometacarpal relationships preserved.
No definite marginal erosions in either hand or wrist on baseline or follow-up. No convincing periostitis, acro-osteolysis, carpal collapse or inflammatory proliferative bone formation.
On follow-up, very mild scattered non-erosive interphalangeal contour irregularity / marginal spurring, most conspicuous at a few DIP joints and the thumb IP joint, low-grade degenerative in appearance — subtle, not associated with erosive change. No definite inflammatory interval change.
Mild hallux valgus with mild medial first-metatarsal-head prominence / bunion-type morphology. First MTP joint space preserved to minimally narrowed, without erosive change. Lesser MTP and IP joint spaces preserved. Midfoot alignment maintained. No focal erosions, periostitis or inflammatory proliferative change. Ankle mortise/alignment preserved; no tibiotalar erosive change.
Compared with baseline (2025): no convincing interval structural progression.
Mild hallux valgus with mild medial first-metatarsal-head prominence / bunion-type morphology. First MTP joint space preserved to minimally narrowed, without erosive change. Lesser forefoot joint spaces preserved. Midfoot alignment maintained. Tiny plantar calcaneal enthesopathic spur present. No convincing erosive change in forefoot, midfoot or ankle; mortise/alignment preserved.
Compared with baseline (2025): no convincing interval structural progression; tiny plantar calcaneal spur stable.
Longitudinal peripheral radiographs from 2025 and 2026 show no radiographic joint damage from RA. No erosions, inflammatory joint-space loss, periostitis or other destructive inflammatory changes are identified in the hands/wrists or feet/ankles, and there is no convincing interval progression over this ~14-month period. Mild incidental noninflammatory findings include bilateral mild hallux valgus/bunion-type morphology, very subtle scattered non-erosive interphalangeal degenerative-type spurring, and a stable tiny left plantar calcaneal spur. Overall imaging remains most consistent with a non-erosive, structurally stable peripheral study. Pattern tags: non-erosive / no radiographic RA damage / mild incidental mechanical-degenerative findings. Progression tag: stable / no structural progression.

This serial peripheral dataset demonstrates a non-erosive, structurally stable profile with zero quantified inflammatory damage at both time points and zero interval destructive progression. The visible burden is confined to mild bilateral first-ray valgus/bunion morphology, trace non-erosive interphalangeal spurring on follow-up, and a stable tiny left plantar heel spur. Age-adjusted burden remains very low, symmetry remains high, and the temporal stability profile is strongly preserved. No radiographic signal of evolving erosive rheumatoid damage is identified on the available studies.
RheumaView™ is a physician-curated reporting assistant and not an FDA-approved diagnostic device. Outputs support clinical decision-making; the treating physician retains full responsibility. Methods reference validated scoring systems and internal QA metrics as defined in the Master Protocol and annexed specifications.
The same architecture renders at controllable depth as a case gets harder. Each tier contributes and compounds; this is not a statement about accuracy.
A single timepoint read in depth — full descriptor coverage, per-joint grading and mimic-control on one study.
Two or more timepoints compared on a shared structural frame; interval deltas and stability are made explicit. Coverage compounds across dates.
Radiograph combined with US / MRI / DEXA; cross-modality coverage adds activity and bone-density dimensions the radiograph alone cannot carry.
