ABSTRACT
A 78-year-old man was referred to our hospital with an abnormal shadow on chest X-ray during a routine medical checkup. Contrast-enhanced computed tomography (CT) scan showed a mass in the left lower lobe, and bronchial brushing revealed it to be squamous cell carcinoma. Although we considered surgical treatment as there was no lymph node involvement or distant metastases, the preoperative CT with contrast enhancement showed a mass in the left ventricle. An FDG-PET scan showed an increased uptake in the cardiac mass, and we diagnosed this as a cardiac metastasis. He was treated with chemotherapy and palliative irradiation but died after nine months of treatment. It is rare for a cardiac metastasis of lung cancer to be diagnosed before the patient’s death, and an FDG-PET is considered effective for this diagnosis.
