CTICasesViral Pericarditis (Second Example)
Imaging findings
A chest radiograph shows cardiomegaly (a 'large heart'). CT reveals a pericardial effusion with some pericardial enhancement. Consistent with the previous case, a left pleural effusion is seen, which is larger than the smaller right pleural effusion.
Key takeaways
This case provides a reinforcing example of viral pericarditis, demonstrating pericardial effusion and enhancement. The observation of a predominant left pleural effusion in the setting of pericardial inflammation is a consistent and diagnostically useful sign, supporting the diagnosis of pericarditis, especially in the context of viral causes that are common in summer months.
