Ultrasound Case: Cuboidal Bursitis Diagnosis: Cuboidal Bursitis. History: None Findings: Patient w/elbow pain and palpable mass over the anterior aspect of the elbow. Fluid and soft tissue are present along the deep surface of the biceps tendon (arrows). The biceps tendon (t, arrow heads) is intact. BR=brachialis muscle, BM=biceps muscle, T=trochlea.

The close proximity of the brachial artery (a) to the bursa is evident. On the right, injection of corticosteroid/anesthetic mixture is performed in real-time, showing mild distension of the bursa with the therapeutic mixture.
