Abstract We reported the case of a 33‐year‐old male who presented a dengue infection complicated by spontaneous coronary artery intramural hematoma associated with acute myocarditis. The initial presentation was a typical acute coronary syndrome with ST‐segment elevation. Coronary angiography and endocoronary optical coherence tomography confirmed the diagnosis of left anterior descending artery intramural hematoma. Cardiac magnetic resonance imaging revealed not only typical ischaemic injury but also lesions of acute myocarditis confirmed by native T1‐ and T2‐mapping, sub‐epicardial late gadolinium enhancement and pericardial effusion. This case highlights the multiple cardiac damages caused by dengue virus, their possible association (coincidental or linked?), and the impact of multimodal imaging on diagnosis and management.
