[Non-Hodgkin cardiac lymphomas]

Cardiac non-Hodgkin lymphoma (CNHL) is a rare extranodal lymphoma with a poor prognosis. Secondary cardiac lymphoma is more frequent than primary cardiac lymphoma. CNHL often involves the right side of the heart. Diagnosis of CNHL can be suggested by echocardiography and magnetic resonance imaging. Cytological examination of pericardial fluid or histological of cardiac tissue is essential. The majority of cases are diffuse B-cell lymphoma. A prompt immediate diagnosis and early treatment are essential for better outcome. Management should be individualized and the most effective treatment is chemotherapy containing anthracycline variably combined with radiotherapy. A multidisciplinary approach is essential to the successful treatment of CNHL.

Lymphoma presenting as severe left ventricular systolic dysfunction: a case report

Lymphoma involving the heart is rare. This is a case report on non-Hodgkin lymphoma where the patient presented for the first time with heart failure and severe left ventricular systolic dysfunction due to lymphoma infiltrating the heart muscle and had simultaneous bilateral involvement of kidneys. This type of presentation has never been described in world literature and is the first reported case.

Cardiac tamponade and paroxysmal third-degree atrioventricular block revealing a primary cardiac non-Hodgkin large B-cell lymphoma of the right ventricle: a case report

INTRODUCTION

Primary cardiac lymphoma is rare.

CASE PRESENTATION

We report the case of a 64-year-old non-immunodeficient Caucasian man, with cardiac tamponade and paroxysmal third-degree atrioventricular block. Echocardiography revealed the presence of a large pericardial effusion with signs of tamponade and a right ventricular mass was suspected. Scanner investigations clarified the sites, extension and anatomic details of myocardial and pericardial infiltration. Surgical resection was performed due to the rapid impairment of his cardiac function. Analysis of the pericardial fluid and histology confirmed the diagnosis of non-Hodgkin large B-cell lymphoma. He was treated with chemotherapy.

CONCLUSION

The prognosis remains poor for this type of tumor due to delays in diagnosis and the importance of the site of disease.
