• Fig B 16-1 Calcific tendinitis. Frontal view of the shoulder demonstrates amorphous calcium deposits (arrows) in the supraspinatus tendon.

• Fig B 16-2 Hyperparathyroidism. Dense mass of tumoral calcification in joint capsules and periarticular soft tissues of the lateral aspect of the foot in a patient with renal osteodystrophy.

• Fig B 16-3 Scleroderma. Clumps of calcification about the shoulder joints (arrows). Note the reticulonodular interstitial pattern at both lung bases. The surgical clips overlying the right apex are from a cervical sympathectomy for the treatment of associated Raynaud's phenomenon.

• Fig B 16-4 Tumoral calcinosis. (A) Supine view demonstrates a large, irregular calcific mass with some relatively lucent areas in the proximal thigh. (B) Upright view shows sedimentation in the liquid-filled cysts (arrow), with absence of sedimentation in the more amorphous gritty deposits.29

• Fig B 16-5 Calcinosis universalis. Dense calcific deposits in the soft tissues on the ulnar aspect of the thumb.

Fig B 16-6 Gout. (A) Frontal and (B) lateral views demonstrate massive deposition of calcium in a long-standing tophaceous lesion about the elbow.

• Fig B 16-7 Myositis ossificans. Marked heterotopic bone formation about the hip joint in a patient with paralysis.

Fig B 16-8 Pellegrini-Stieda disease. Post-traumatic ossification (arrows) along the femoral condyle.
