Positron emission tomography (PET) using 18F-fluorodeoxyglucose (18F-FDG) is useful for staging non-small cell lung cancer (NSCLC), decide the appropriate initial management, and evaluate the response to therapy. Metastatic spreading is very common during the course of NSCLC and principal localization sites include: regional and mediastinal lymph nodes and organs such as the contralateral lung parenchyma, bone, brain, adrenal gland, pleura, and liver. Myocardial localizations are very rare, often asymptomatic, and difficult to diagnose. For this reason, only a few cases are reported in the literature. Here, we report a case of an asymptomatic patient affected by locally advanced NSCLC and high metabolic lesion of the interventricular septum.
