CTICasesAcute Myocardial Infarct with Microvascular Obstruction
Imaging findings
Severe, extensive infarction in the left main territory with profound microvascular obstruction (black areas on delayed enhancement sequence) and potential SCAD (Spontaneous Coronary Artery Dissection).
Key takeaways
Microvascular obstruction indicates a poor prognosis; clinicians should consider underlying structural causes like SCAD in young patients with severe infarcts even when initial reports suggest vasospasm.
