Paravertebral ossification in psoriasis and Reiter's disease
The British Journal of Radiology
|August 1, 1975
Summary
Paravertebral ossification (PVO) can be a key indicator in diagnosing psoriatic arthropathy and Reiter's disease, even before other symptoms appear. This radiological sign is valuable when joint X-rays are unclear, aiding early detection of these inflammatory conditions.
Area of Science:
- Rheumatology
- Radiology
- Immunology
Background:
- Psoriatic arthropathy and Reiter's disease are inflammatory conditions affecting joints.
- Radiological assessment is crucial for diagnosis, but early signs can be subtle.
- Paravertebral ossification (PVO) has been described in these conditions.
Purpose of the Study:
- To evaluate the significance of paravertebral ossification (PVO) as a radiological sign in psoriatic arthropathy and Reiter's disease.
- To determine if PVO can be the primary or sole radiological abnormality.
- To assess the diagnostic value of PVO when sacro-iliac or peripheral joint involvement is equivocal.
Main Methods:
- Retrospective study analyzing radiological findings.
- Review of cases with psoriatic arthropathy and Reiter's disease.
- Focus on identifying paravertebral ossification and non-marginal syndesmophytes.
Main Results:
- Paravertebral ossification (PVO) can be the sole or major radiological abnormality.
- PVO is a significant finding, comparable to peripheral joint involvement in the hands.
- This radiological sign may be present before the onset of the characteristic psoriatic rash.
Conclusions:
- Paravertebral ossification (PVO) is a valuable radiological marker for psoriatic arthropathy and Reiter's disease.
- PVO aids in diagnosis, especially when sacro-iliac joints appear normal or equivocal.
- Early identification of PVO may facilitate timely diagnosis and management.
