There is an ill-defined subcutaneous collection with mobile echoes in the posterior elbow region; measuring about 35 x 24 x 13 mm (volume 6 cc). There is no wall formation around the collection. It abuts the olecranon process of the ulna without causing bony erosion. There is diffuse subcutaneous edema in the distal arm and proximal forearm. Local hypervascularity is present. The triceps tendon shows normal echopattern.
