title: [Malignant lymphoma with various cardiac manifestations: a case report].
abstract: A 49-year-old woman presented with malignant lymphoma manifesting as dyspnea, palpitation and leg edema. Chest radiography demonstrated cardiomegaly, electrocardiography(ECG) showed first degree atrioventricular block, and echocardiography showed concentric left ventricular hypertrophy with granular sparkling texture and mild pericardial effusion. The diagnosis was malignant lymphoma(B-cell) based on lymph node biopsy. Chemotherapy(CHOP) was performed under a suspected diagnosis of cardiac invasion of malignant lymphoma. Immediately after chemotherapy, ECG showed complete atrioventricular block with sinus arrest, ventricular fibrillation and atrial fibrillation. ECG was normalized after 2 weeks on chemotherapy. Left ventricular hypertrophy was improved and pericardial effusion disappeared. However, she died of recurrence of malignant lymphoma on day 116.
