CTICasesViral Pericarditis
Imaging findings
CT angiography, performed for chest pain, reveals a sizable pericardial effusion. The IVC and SVC are enlarged, and the ventricles show suboptimal filling, suggesting early tamponade. Small pleural effusions are also present, predominantly on the left.
Key takeaways
Viral pericarditis often follows a viral prodrome and presents with chest pain, leading to pericardial effusion which can progress to features of early cardiac tamponade. A helpful diagnostic clue is the presence of an accompanying left-sided pleural effusion, often larger than any right-sided effusion, in cases of pericardial inflammation. Conservative therapy is often effective.
