Key result
CMR accurately diagnoses rare cases of norovirus-linked viral myocarditis presenting with acute chest pain.
Why the study?
Viral myocarditis secondary to norovirus is rarely reported and poses diagnostic challenges in acute chest pain with troponin elevation.
Highlights the utility of cardiac magnetic resonance in diagnosing rare norovirus-induced viral myocarditis in patients presenting with acute chest pain and elevated troponin.
Consider CMR in acute chest pain with troponin elevation; extends differential to norovirus myocarditis but should not yet change practice.
We present a rare case of viral myocarditis secondary to a rarely reported cause, norovirus. This case highlights the diagnostic challenges associated with acute chest pain accompanied by troponin elevation. We discuss the significance of advanced imaging techniques, particularly cardiac magnetic resonance, in the diagnosis of this condition.

Blake et al. (2026) studied this question. Norovirus is a rare cause of viral myocarditis presenting with acute chest pain and troponin elevation, requiring cardiac magnetic resonance imaging for accurate diagnosis.
