Asemptomatik sakroiliit düz grafilerde psoriasisli hastaların sadece 4(%14.8) ünde olmasına karşılık bilgisayarlı tomografide 8(%29,6) inde saptanırken, kontrol grubunda ise hiç rastlanmadı(%0). Sakroiliitin varlığı ya da yokluğu ile hastaların yaşı, cinsi ve hastalık süresi arasında korelasyon saptanmadı.

Sonuçta psoriatik hastalarda asemptomatik sakroiliit yaygın olarak görülmektedir ve bunun semptomatik bir spondilartropatiye progresyon göstereceği belli değildir. Bilgisayarlı tomografi sakroiliak eklemlerin değerlendirilmesinde etkili bir metottur.

Plain film radiographs and computed tomography scans of sacroiliac joints were performed in 27 asymptomatic psoriatic patients and in 21 healthy controls and evaluated by two radiologists. The severity of sacroiliitis was scored using the New York grading system.

Sacroiliitis was observed on plain film radiography in 4(14,8%) and computed tomography revealed the presence of asymptomatic sacroiliitis in 8 (29,6%) of 27 psoriatic patients, whereas none (0%) in controls. No correlation was observed between the presence or absence of sacroiliitis, and the age and sex of patients, or duration of disease.

As a conclusion, asymptomatic sacroiliitis is common in psoriatic patients, whether its presence will predict a progression to an overt spondylarthropathy is not clear, and computed tomography is an effective method of examination of the sacro-iliac joints.
