Occult pneumomediastinum in a SARS patient presenting as recurrent chest pain and acute ECG changes mimicking acute coronary syndrome.

Objective: Severe acute respiratory syndrome (SARS) is a newly emergent disease due to a novel coronavirus, which caused outbreaks worldwide.
Methodology: We report a SARS patient who had developed recurrent chest pain and acute T-wave inversion over the precordial leads on electrocardiography (ECG).
Results: She developed progressive subcutaneous emphysema a few days later. Her CXR showed features suggestive of pneumomediastinum, which was confirmed by high-resolution CT scan of the thorax.
Conclusion: Pneumomediastinum should be considered in SARS patients as a possible cause of chest pain and ECG changes that mimic acute coronary syndrome.
