Behcet's Disease is a systemic vasculitis of unknown etiology. Articular involvement is a well-recognized feature, that is generally intermittent, self-limiting, non-erosive, non-destructive, and non-deforming, usually monoarticular or symmetrically oligo-articular subacute structive, arthritis. While knees, ankles and wrists are most commonly affected, elbow involvement is very rare. Previous descriptions of articular involvement have been mostly limited to conventional radiographic findings. We report magnetic resonance imaging (MRI) findings of pathologically proven acute synovitis on chronic arthritis of the left elbow in a 25 year-old man with Behcet's disease, who followed up for 9 years.
