Chondrocalcinosis, Tumoral Calcinosis, synovial chondromatosis and calcific tendonitis

Dr. Ebraheim’s educational animated video describes differences between Chondrocalcinosis, Tumoral Calcinosis, synovial chondromatosis and calcific tendonitis
These 4 entities may sound a little bid a like, however they are 4 different entities.
• Chondrocalcinosis:
- Or pseudo gout, it is a metabolic disease due to deposition of calcium pyrophosphate dehydrate crystals in the hyaline cartilage or fibrocartilage (CPPD).
- It usually affects older patients.
- The crystals are rhomboid shaped and positively birefringent, crystals will be blue when placed under polarized light.
- The Uric Acid crystals are needle like and negatively birefringent.
- So you will find calcification of the fibrocartilage structures such as the meniscus in the knees or the triangular fibrocartilage complex (TFCC) in the wrist.
- If you see an X-ray and find calcification of the meniscus of the knee, or calcification of the triangular fibrocartilage of the wrist, this means that the patient has a pseudo gout, or chondrocalcinosis.
- Chondro means cartilage (hyaline or fibrocartilage), calcinosis means calcification.
• Tumoral Calcinosis:
- Is a rare condition that may be hereditary.
- Affect people of African origin usually more than others, and more in females.
- Tumoral Calcinosis means: calcium deposition which may resemble a tumor.
- Calcium is usually deposited in the soft tissue within the particular area around the joint.
- Calcium accumulates outside the joint.
- It is usually seen in patients on dialysis.
- Growth doesn’t have any malignant cells.
- Usually painless.
- Swelling around the joint may limit movement and ambulation of the patient.
- Usually deposited around the shoulders and hips.
- Wide resection to avoid recurrence.
• Synovial Chondromatosis:
- It is a problem of the synovium (intra- articular).
- Usually associated with cartilaginous metaplasia.
- Usually in male patients.
- It occurs usually in weight bearing joints.
- X-ray will show loose bodies inside of the joint.
- This condition is benign.
- Usually only requires symptomatic treatment unless the condition is painful.
- If it is painful, removal of all loose bodies is required.
- In this case the synovial tissue changes into cartilage or chondroid tissue, which is not cancer, if the condition of synovial chondromatosis is painful, you do open or arthroscopic synovetomy and remove all of the loose bodies.
• Calcific Tendonitis:
- Calcification of the tendon.
- Usually occurs within the rotator cuff tendons of the shoulder.
- Causes pain and inflammation.
- Occurs more in females, in diabetic patients.
- The supraspinatus tendon is most often involved.
- Usually diagnosed with X-ray.
- Calcium deposits are visible on X-ray.
- Usually the calcifications are found about 1-1 ½ cm from the insertion of the supraspinatus tendon.
- MRI will show low signal intensity of the calcium deposits.
- Calcification and degeneration is usually associated with subacromial impingement.
