“…In contrast, cardiac metastases from any histologic tumor types are 20- to 40 times more common [2]. Although it has been reported that lymphomas have cardiac metastases in 8.7% to 27% of cases, a mediastinal DLBCL infiltrating the heart and presenting as a large intracardiac mass is extremely rare [1,3]. This presentation was seen in our patient.…”

“…Signs and symptoms may be non-specific and include dyspnea, arrhythmias, pericardial tamponade or effusion, left ventricle or right ventricle outflow tract obstruction, tumor embolization, and valvular heart disease [3]. Other findings may include superior vena cava syndrome, peripheral embolization, and an intracardiac thrombus [6].…”

“…Chest X-ray may demonstrate cardiomegaly and signs of heart failure, which are non-specific findings [7]. Subsequent CT and magnetic resonance imaging will help determine size, spread of tumor, mediastinal involvement, and blood flow obstruction [3]. A PET/CT is also completed for staging and prognostication.…”

“…In the past, thoracotomy was done for tissue biopsy however less invasive tests are now used. These include TEE with biopsy, percutaneous intracardiac biopsy with combined fluoroscopy, endomyocardial biopsy, and pericardial fluid testing [3]. Pericardial fluid cytological testing may be used if pericardial effusion is present [6].…”

A Rare Case of Diffuse Large B Cell Lymphoma Presenting as a Cardiac Mass

et al. 2019

Rare disease Background: Primary mediastinal diffuse large B cell lymphoma (DLBCL) presenting as a large intracardiac tumor is extremely rare and has not been significantly reported in the literature. Cardiac lymphoma consists of 2 subtypes: mediastinal DLBCL invading the heart and primary cardiac lymphoma. Both subtypes have a poor prognosis and are treated similarly. Mediastinal DLBCL is a life-threatening condition that, if diagnosed early, has a better survival rate. This is a rare case of a mediastinal DLBCL invading the right atrium as a large intracardiac mass, causing partial obstruction of the tricuspid valve without hemodynamic compromise. Case Report: A 57-year-old female presented with unintentional weight loss, fatigue, exertional dyspnea, and cough for 8 weeks. Transesophageal echocardiogram showed a mass (3.5×3.5 cm) in the posterior wall of the right atrium partially obstructing the tricuspid valve. Biopsy revealed DLBCL. Given new-onset lymphoma, a human immunodeficiency virus (HIV) test was done and came back positive. CD4 count was 100 cells/mm 3. Chemotherapy was initiated with rituximab, cyclophosphamide, epirubicin, vincristine, and prednisone (R-CHOP). Highly active anti-retroviral (HAART) therapy was started for HIV. After treatment with R-CHOP and HAART, the patient had complete resolution of the mass and symptoms on follow-up imaging and evaluation at 6 months. Conclusions: Mediastinal DLBCL invading the heart is a life-threatening form of non-Hodgkin's lymphoma (NHL) and early diagnosis and treatment is critical as prognosis is poor especially if diagnosed in later stages of the disease. Testing for HIV is important as 5% of HIV patients are susceptible to developing NHL.

“…Secondary cardiac involvement of lymphoma is relatively common, reported in 8.7-25% of documented clinical cases of lymphoma ( 1 ). Nevertheless, manifestations of cardiac involvement of lymphoma are often subclinical, thus, cardiac involvement as an initial presentation of malignant lymphoma is rare ( 2 , 3 ).…”

Secondary Cardiac Lymphoma Presenting as Sick Sinus Syndrome and Atrial Fibrillation Which Required Leadless Pacemaker Implantation

et al. 2021

Cardiac involvement of malignant lymphoma is relatively common, although such a phenomenon has subclinical manifestations that are difficult to detect. We herein describe a patient with atrial fibrillation and sick sinus syndrome as the main symptoms. Computed tomography showed a mass in the right atrium extending into the superior vena cava (SVC). We implanted the patient with a leadless pacemaker. Transvenous biopsy revealed a diffuse large B-cell lymphoma. The patient was treated successfully with chemotherapy including rituximab. This case suggested that cardiac lymphoma may cause sick sinus syndrome, and leadless pacemaker implantation is a safe treatment option in patients with partial SVC obstruction.

Intracardiac diffuse large B-cell lymphoma: an unexpected diagnosis

Intracardiac lymphomas are exceedingly rare accounting for only 1% of all primary cardiac tumours. Historically, due to their insidious development and non-specific clinical presentation, the diagnosis has been challenging with most cases being confirmed on post-mortem examination. Our case report details the experience of a previously fit and active woman in her 60s who presented with gradual onset exertional dyspnoea. Through a series of multimodal imaging tools (including echocardiogram, cardiac MRI, CT and positron emission tomography-CT) and biopsy, we confirmed the diagnosis of intracardiac diffuse large B-cell lymphoma. Our patient was managed with chemotherapy and went on to demonstrate excellent radiological response with near-complete resolution of the intracardiac mass. Subjectively, our patient reported significant improvement in exercise tolerance within weeks of commencing treatment.
