title: [A case report of primary cardiac lymphoma presented with marked cardiac accumulation of 67Ga-citrate].
abstract: A case of primary malignant lymphoma of the heart is reported. The patient who was a 67-year old male presented with dyspnea on exertion. The chest X-ray film showed an enlarged cardiac silhouette. UCG showed massive pericardial effusion and a mass in the right atrium. Although pathological confirmation was failed in the cardiac biopsy, malignant cardiac tumor was strongly suspected by a gallium scintigraphy, which showed marked accumulation in the heart. After irradiation therapy the cardiac tumor diminished in size and the cardiac 67Ga-citrate accumulation also disappeared. Multiple skin metastases, however, were soon noted, and a subsequent skin biopsy confirmed the diagnosis of malignant lymphoma. He died within 11 months in spite of systemic chemotherapy. Primary cardiac lymphoma is extremely rare, but this case suggested the cardiac mass with positive gallium scintigraphy have a possibility of cardiac lymphoma.
