title: Primary cardiac lymphoma mimicking infiltrative cardiomyopathy.
abstract: Primary cardiac lymphoma is a rare malignancy which has been described as thickened myocardium due to the infiltration of atypical lymphocytes and accompanying intracardiac masses. Here, we report a case of a primary cardiac lymphoma without demonstrable intracardiac masses, mimicking infiltrative cardiomyopathy. A 40-year-old male presented with exertional dyspnoea and was diagnosed as having restrictive cardiomyopathy with severely decreased LV systolic function. Endomyocardial biopsy was performed and the diagnosis of primary cardiac lymphoma was confirmed. After appropriate chemotherapy, he recovered his systolic function fully.
