[Diagnosis of psoriatic osteoarthropathy: comparison of clinical, radiologic and scintigraphic findings].
Among the group of seronegative spondarthritides psoriatic osteoarthropathy can be differentiated from rheumatoid arthritis as a separate disease with generalized osseous proliferation. 33 cases were evaluated and clinical data, X-ray films and nuclear bone scans were compared. Pathological alterations in the bone structure can be found by bone scintigraphy already at very early, even subclinical stages of the disease, thus allowing early diagnosis. In a high percentage of our cases pathological alterations could be demonstrated by scintigraphy long before they were revealed on X-ray films. Scintigraphic methods may help to evaluate the activity of the disease. Furthermore, in many of our cases, localization and concentration of the tracer in the skeleton were so typical, that they may be considered pathognomonic for psoriatic osteoarthropathy. Thus bone scanning appears to be a useful tool for the diagnostic evaluation and follow up in cases of psoriatic arthropathy, in particular if the low exposure to radiation is taken into account.
