Acute myocardial infarction as presentation of an infiltrative lung neoplasia

AbstractWe report the case of a 51-year-old woman who presented with acute myocardial infarction as initial symptom of an infiltrative lung neoplasia. The patient was admitted to our center following an out-of-hospital cardiac arrest due to ventricular fibrillation which was cardioverted. On electrocardiography an anterior wall ST-elevation was found and urgent coronary angiography was performed. Left anterior descending coronary artery was occluded and after thrombus aspiration, an image of diffuse loss of lumen diameter and absence of coronary branches was compatible with an extrinsic compression. Such findings along with a lingula consolidation on chest X-ray examination suggested a thoracic neoplasia. Enhanced-chest computed tomography showed a mass located in the lingula with extensive mediastinal infiltration involving pericardium and myocardium. Anatomopathologic examination confirmed the presence of lung adenocarcinoma.
