This report describes the ultrasonographic and CT arthrography (CTA) findings in biceps brachii tendon rupture in two dogs. Ultrasonographic examination of the affected shoulder joints preceded advanced imaging in both dogs and was suggestive of partial or complete avulsion/rupture of the biceps brachii tendon and chronic tendonitis. Subsequent CTA demonstrated complete rupture/avulsion of the biceps brachii tendon in the affected shoulder joints in both dogs. The biceps brachii tendon could be identified as a contrast filling defect within the synovial space. Pooling of the contrast medium was identified close to its origin and was suggestive of biceps brachii tendon rupture in both cases described here. In this case report, avulsion of the biceps brachii tendon was suspected using ultrasonography alone but confirmed by CTA.
