Rupture of the long head of the biceps tendon frequently is encountered in the setting of coexisting rotator cuff pathology and chronic impingement, but traumatic rupture is occasionally seen, as in this case. Signs and symptoms are not always diagnostic, and MRI or MR arthrography can be a useful tool for evaluation of the tendon in difficult cases. Ideally, an empty bicipital groove is seen, indicating absence of the tendon and rupture. Scar tissue within the groove can be problematic, and correlation with oblique coronal and sagittal images is always recommended. The superior labrum at the attachment of the bicipital anchor should always be inspected carefully, as this is the most common site of rupture, and there may be an associated tear of the superior labrum. Magnetic resonance arthrography is not necessary for diagnosis in most cases, but will provide better visualization of the tendon and bicipital-labral complex.
