18-year-old male with intermittent left elbow swelling. There is mild increased signal intensity and enhancement in the distal triceps tendon at its insertion on the olecranon with perhaps minimal signal abnormality in the underlying bone suggestive of a mild enthesitis. The bone marrow signal intensity is otherwise unremarkable. We see no evidence of an osteochondral defect. The remaining tendons are unremarkable. Ligaments are unremarkable.There is a small elbow joint effusion. There is mild synovial enhancement suggesting mild synovitis, but the degree of synovial inflammation is decreased when compared to the prior study from 2013. We see no evidence of erosions.There are small foci of signal void within the elbow joint and adjacent soft tissues which may reflect prior intervention.
1. Small joint effusion with interval decrease in synovial inflammation when compared to the prior study.2. There is perhaps a mild enthesitis of the triceps at its insertion on the olecranon.
