42-year-old female with pain with movement. Evaluate for tendinopathy. LIGAMENTS: The ulnar collateral ligament and radial collateral ligament appear intact.TENDONS: Increased signal intensity at the origin of the common extensor tendon is compatible with tendinosis ("lateral epicondylitis"). There is minimal edema within the soft tissues adjacent to the common flexor tendon at its origin but the tendon itself appears normal. The biceps and brachialis tendons appear normal. The triceps tendon appears normal.ARTICULAR SURFACES AND BONE: Bone marrow signal intensity is normal. We see no osteochondral defects. There is a small amount of fluid within the joint but no frank effusion. SURROUNDING STRUCTURES: The muscles of the elbow appear normal. There is increased signal intensity on fat-suppressed T2-weighted images of the ulnar nerve within and just proximal to the cubital tunnel which could represent mild neuritis although this is equivocal.
1.Mild tendinosis of the common extensor tendon (mild "lateral epicondylitis").2.Mild increased signal intensity of the ulnar nerve may reflect mild neuritis but this is of questionable clinical significance.
