Mediastinal bronchogenic cyst manifesting as a catastrophic myocardial infarction.
Congenital bronchogenic cysts of the lung and mediastinum develop from the ventral foregut during embryogenesis. These cysts are often incidental radiologic findings in adults, but patients can be seen with symptoms of chest pain, cough, dyspnea, or any combination of these. Acute presentations are unusual and have rarely been reported. We present the unique case of a 36-year-old man seen with an acute coronary syndrome and sudden hemodynamic collapse. The patient sustained a massive and ultimately fatal myocardial infarction, compression of the left main coronary artery by a bronchogenic cyst was demonstrated at postmortem examination. If detected, bronchogenic cysts should be surgically excised to limit associated morbidity and mortality.
