[Primary cardiac lymphoma]. / Primaert, kardialt lymfom.

ABSTRACT

Primary cardiac non-Hodgkin lymphoma is very rare. Results recently published suggest that the prognosis is good, if the lymphoma is diagnosed early. The symptoms are nevertheless unspecific and a clinical investigation is often inconclusive. We report a case of a woman with symptoms of severe dyspnoea at rest, chest pain, and fatigue. The ECG showed a complete atrioventricular block. Magnetic resonance imaging (MRI) revealed a tumour in the right atrium and ventricle. A myocardial biopsy showed malignant non-Hodgkin lymphoma of the diffuse, large cell B-type. The patient was treated with chemotherapy and control MRI after four treatments showed complete regression of the tumour.
