Differential Diagnosis for Deep Scapula Pain Following a Car Wreck
Single Most Likely Diagnosis
- Musculoskeletal strain or sprain (M54.9): This is the most likely diagnosis given the history of a car wreck, which can cause direct trauma or sudden movement leading to strain or sprain of the muscles and ligaments around the scapula.
Other Likely Diagnoses
- Thoracic outlet syndrome (G54.0): The trauma from the car wreck could lead to compression or irritation of the nerves and blood vessels that pass through the thoracic outlet, causing pain in the scapular region.
- Costochondritis (M94.1): Inflammation of the cartilage that connects the ribs to the sternum could be caused by the trauma, leading to pain that might be referred to the scapular area.
- Myofascial pain syndrome (M79.1): This condition, characterized by pain and inflammation of the muscles and their surrounding connective tissue, could be triggered by the physical stress of the car wreck.
Do Not Miss Diagnoses
- Pulmonary embolism (I26.9): Although less likely, a pulmonary embolism could present with sudden onset of chest or back pain and must be considered, especially if there are risk factors such as prolonged immobilization following the accident.
- Aortic dissection (I71.0): This is a life-threatening condition where there is a tear in the aorta's inner layer. It can present with severe, sudden pain in the chest or back and is crucial to diagnose promptly.
- Spinal fracture or injury (S32.0): The force of the car wreck could have caused a fracture or other injury to the spine, which needs to be ruled out due to the potential for serious complications.
Rare Diagnoses
- Tumor (C79.7): Although rare, it's possible that the pain could be related to a tumor affecting the scapula or surrounding structures. This would be an unlikely first consideration without other supporting symptoms or findings.
- Osteomyelitis (M86.9): Infection of the bone is a rare possibility, especially if there was an open wound or other infection risk following the accident.
- Pancreatitis (K85.9): Referred pain from pancreatitis could potentially be felt in the back, including the scapular area, though this would be unusual without other abdominal symptoms.
