Differential Diagnosis for Suspected Calcification of the Rotator Cuff
Single Most Likely Diagnosis
- Calcific Tendinitis: This condition is characterized by the deposition of calcium hydroxyapatite within the tendons of the rotator cuff, leading to pain and inflammation. It is a common cause of shoulder pain and stiffness, making it the most likely diagnosis for suspected calcification of the rotator cuff.
Other Likely Diagnoses
- Tendinosis: A condition involving degenerative changes within the tendons of the rotator cuff, which can sometimes be associated with calcification. It presents with similar symptoms of pain and reduced mobility.
- Bursitis: Inflammation of the bursae surrounding the rotator cuff tendons, which can be associated with calcification and presents with pain and limited movement.
- Rotator Cuff Tear: While not primarily a calcification issue, tears in the rotator cuff can coexist with or lead to calcification and are a common cause of shoulder pain and dysfunction.
Do Not Miss Diagnoses
- Septic Arthritis: Although less likely, septic arthritis of the shoulder joint can present with acute pain and reduced mobility, similar to calcific tendinitis. Missing this diagnosis could lead to severe joint destruction and systemic infection.
- Bone Tumor: Rarely, a bone tumor (benign or malignant) could present with calcification visible on imaging. Missing a malignant tumor could have severe consequences.
Rare Diagnoses
- Dystrophic Calcification in a Paralyzed Muscle: In cases of long-standing paralysis or denervation of the muscles around the shoulder, dystrophic calcification can occur. This is a rare condition and would be considered in the context of a known neurological condition affecting the shoulder.
- Idiopathic Calcification: There are rare instances where calcification occurs without a clear underlying cause or condition, which could be considered if other diagnoses are ruled out.
