Primary Cardiac Lymphoma Presenting With Atrioventricular Block
نویسندگان
چکیده
Primary cardiac lymphomas (PCL) are extremely rare. Clinical manifestations may be variable and are attributed to location. Here, we report on a case of PCL presenting with atrioventricular (AV) block. A 55 year-old male had experienced chest discomfort with unexplained dyspnea and night sweating. His initial electrocardiogram (ECG) revealed a first degree AV block. Along with worsening chest discomfort and dyspnea, his ECG changed to show second degree AV block (Mobitz type I). Computed tomography (CT) scan showed a cardiac mass (about 7 cm) and biopsy was performed. Pathologic finding confirmed diffuse large B-cell lymphoma. The patient was treated with multi-drug combination chemotherapy (R-CHOP: Rituximab, cyclophoshamide, anthracycline, vincristine, and prednisone). After treatment, ECG changed to show normal sinus rhythm with complete remission on follow-up CT scan.

UNLABELLED Primary cardiac lymphoma is very rare, and the most common electrocardiographic finding in this condition is complete atrioventricular block. After electrolytic, metabolic, ischemic, infectious, and traumatic etiologies have been excluded, primary cardiac lymphoma should be consided as a possible cause of reversible atrioventricular block. Most patients with primary cardiac lymphoma ...

Cardiac symptoms as an initial presentation of malignant lymphoma are rarely seen. We report a 42-year-old male patient of primary cardiac lymphoma originating in the left atrium with episodes of syncope. Complete atrioventricular (AV) block was found by electrocardiography, and the patient was admitted for pacemaker implantation. Before permanent pacemaker implantation, transthoracic echocardi...

Primary cardiac lymphoma (PCL) is very rare, and is extremely challenging to diagnose due to nonspecific symptoms. When discovered, the right atrium and ventricle are most commonly affected, while diffuse cardiac involvement is uncommon. PCL is fatal unless promptly diagnosed and treated. Herein, we present the case of a 36-year-old immunocompetent male who presented with a 5-year history of no...

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, e...

We report a patient with cardiac involvement associated with primary amyloidosis presenting marked left ventricular (LV) wall thickening, severely decreased systolic and diastolic function, and complete atrioventricular block (CAVB), who died suddenly of cardiac arrest caused by electro-mechanical uncoupling occurring immediately after permanent pacemaker implantation. Post mortem examination s...
