In a patient with sarcomatoid carcinoma of left main bronchus, a computed tomography scan revealed an abnormal mass in the apex of the left ventricle (LV) (A). Echocardiography showed a well-defined hyperechoic mass in the same region, wall motion was reduced in the apex and posterolateral wall, and there was thinning of the posterior wall (Online Videos 1and 2), suggesting old myocardial infarction and that the mass was due to thrombus.
Then, fluorodeoxyglucose–positron emission tomography (FDG-PET) was performed. Strong accumulation was detected inside the apex, extending into the apical and lateral wall (B), indicating high metabolic activity, which is consistent with tumor invasion. Therefore, the mass was diagnosed as a large intracardiac metastasis.
