XAVIER OLIVEIRA, Jefferson; BRASIL, Sandra Alves; MARCUCCI, Marcelo  e  PANELLI SANTOS, Karina Cecília. Manifestation of psoriatic arthritis in the temporomandibular joint - imaging features. RFO UPF [online]. 2011, vol.16, n.1, pp. 110-113. ISSN 1413-4012.

The psoriatic arthritis is a chronic arthropathy of not fully clarified etiology and pathogenesis that, although rare, can affect the temporomandibular joint. It is defined as inflammatory arthritis associated with psoriasis, chronic and erosive, which is seronegative for rheumatoid factor. Objective: The aim of the study is to review the literature about psoriatic arthritis imaging fetures at the tempormandibular joint. Literature review: The articular involvement can vary from a mild synovitis to a progressive erosive arthropathy. The development of differential diagnosis can be a challenge, a detailed history and general physical examination of the patient are extremely important to get the diagnosis, and should be considered when evaluating the images of articular lesions. The use of computed tomography in the diagnosis of psoriatic arthritis should be part of routine evaluation. Magnetic resonance imaging, ultrasound and scintigraphy have important role in early diagnosis of psoriatic arthritis in the temporomandibular joint, in tracking the progress of the disease and may also indicate a change in treatment. Final considerations: However, it is concluded that the psoriatic arthritis involving the temporomandibular joint is characterized by pain and functional limitation, causing progressive destruction of articular tissue and bone components, clearly indicated on imaging examinations. Thus, magnetic resonance imaging is the key to the diagnosis, monitoring the progress of the disease and the guidance on its treatment.
