An 80-year-old man was diagnosed as having diffuse large B cell lymphoma in the posterior cervix on the basis of results of biopsy performed in another hospital, and he was admitted to our hospital for chemotherapy. Echocardiography revealed a mass in the pericardium, pericardial effusion, and hypokinesis of the left ventricular inferior wall. After four courses of chemotherapy, echocardiography showed reduction of the mass in the pericardium and improvement in the left ventricular inferior wall movement. Moreover, CT showed reduction of the mass in the posterior cervix and pericardium. However, three months later, the mass in the pericardium increased in size and the left ventricular inferior wall movement was reduced in echocardiography. Moreover, PET-CT showed an increase in the mass of the posterior cervix and pericardium again. The posterior cervical mass and pericardial mass decreased in size with chemotherapy. Therefore, we diagnosed the patient as having malignant lymphoma in the posterior cervix with cardiac infiltration. Recent reports have revealed that echocardiography showed pericardial effusion, ventricular wall thickness, and myocardial mass in cardiac infiltration of the hematopoietic tumor. In our patient, the mass in the pericardium and hypokinesis of the left ventricular inferior wall were revealed by echocardiography. Thus, echocardiography is an important tool for diagnosing cardiac infiltration of malignant lymphoma.
