Right elbow locking. Prior MRI dated 1/30/2011 demonstrated an old osteochondral defect/degenerative cyst. Prior MRI also demonstrated prominence of synovial fat versus intra-articular loose bodies. There is no significant elbow effusion.The noncontrast CT appearance of the common flexor and extensor tendons is normal. The noncontrast CT appearance of the biceps, brachialis, and triceps is normal.No fluid collections within the soft tissues.Small subchondral lucencies in the anterior aspect of the capitellum are again seen, and given differences in technique appear unchanged from the prior MRI. These may represent degenerative cysts, or old osteochondral defects. The overlying bone plate is intact, suggesting stability. A small defect more posteriorly in the capitellum may represent a normal variant "pseudodefect."No new osseous defects. No fractures.The trochlea, olecranon, and radial head appear normal.Adherent to the posterior wall of the olecranon fossa are a cluster of small 3-mm foci with central fat density, and a rim of calcification. These correspond to the finding on the prior MRI and in keeping with small intra-articular loose bodies. No additional intra-articular loose bodies are seen.
1. Cluster of small 3-mm foci with central fat density and rim calcification adherent to the posterior wall of the olecranon fossa. These correspond to the finding on prior MRI and are in keeping with small intra-articular loose bodies.2. Small unchanged subchondral cysts in the anterior aspect of the capitellum representing degenerative cysts or old osteochondral defects. The overlying bone plate is intact, suggesting stability.
