Differential Diagnosis for Swelling with Pain in the Sternoclavicular Joint
- Single most likely diagnosis
- Septic arthritis: This is a common and serious condition that can cause swelling and pain in the sternoclavicular joint, especially if there is a history of trauma, infection, or intravenous drug use. Prompt diagnosis and treatment are crucial to prevent long-term damage.
- Other Likely diagnoses
- Osteoarthritis: Wear and tear on the joint can cause pain and swelling, especially in older adults.
- Rheumatoid arthritis: This autoimmune disorder can cause inflammation and pain in the sternoclavicular joint, among other joints.
- Trauma: Direct blows to the joint or indirect forces from falls or car accidents can cause swelling and pain.
- Costoclavicular syndrome: Compression of the nerves and vessels between the clavicle and the first rib can cause pain and swelling in the sternoclavicular joint.
- Do Not Miss (ddxs that may not be likely, but would be deadly if missed.)
- Pneumomediastinum: Air in the mediastinum can cause pain and swelling in the sternoclavicular joint, and can be a sign of a life-threatening condition such as a ruptured esophagus or trachea.
- Aortic dissection: A tear in the aorta can cause pain and swelling in the sternoclavicular joint, and is a medical emergency.
- Osteomyelitis: Infection of the bone can cause pain and swelling in the sternoclavicular joint, and can be life-threatening if left untreated.
- Rare diagnoses
- Relapsing polychondritis: A rare autoimmune disorder that can cause inflammation and destruction of cartilage, including the sternoclavicular joint.
- SAPHO syndrome: A rare condition that can cause inflammation and pain in the sternoclavicular joint, among other joints.
- Tietze's syndrome: A rare condition that can cause inflammation and pain in the cartilages of the ribs, including the sternoclavicular joint.
