Reason: ro partial biceps tendon tear History: biceps pain LIGAMENTS: The proximal fibers of the radial collateral ligament proper appear thickened and are of increased signal intensity which may reflect a chronic tear. The ulnar collateral ligament appears normal.TENDONS: The tendon of the long head of the biceps appears normal as does the brachialis. The common flexor tendon appears intact. There is increased signal intensity within the anterior undersurface fibers of the common extensor tendon compatible with a partial-thickness undersurface tear.ARTICULAR SURFACES AND BONE: Mild osteoarthritis affects the elbow with small defects of the articular cartilage and subchondral cysts within the distal humerus and proximal ulna.SURROUNDING STRUCTURES: There is mild increased signal intensity within the brachioradialis, supinator, and to a lesser degree the pronator teres muscles. We see no masses. There is no fatty atrophy.ADDITIONAL
1. Normal-appearing biceps tendon without tear.2. Increased signal intensity within the anterior fibers of the common extensor tendon suggesting a partial thickness undersurface tear / mucoid degeneration with thickening and increased signal intensity of the underlying proximal fibers of the radial collateral ligament proper which may also reflect an underlying chronic tear. The current clinical significance of this finding is uncertain.3. Mild edema type signal within the brachioradialis, supinator, and pronator teres muscles without clear etiology.
