Primary cardiac lymphoma is an extranodal malignant lymphoma of any cell type involving only heart and pericardium without dissemination. Patients usually present symptoms of heart failure, arrhythmias, pericardial effusion and cardiac tamponade. Diagnosis of primary cardiac lymphoma can be performed by echocardiogram, CT and MRI and cytologic examination of pericardial effusion or transvenously biopsied cardiac tissue. Prognosis of primary cardiac lymphoma is poor. Because of poor prognosis, early diagnosis and complete surgical excision is essential and postoperative systemic chemotherapy or radiotherapy is useful. In this case extensive tumor infiltration on the right ventricle and atrioventricular groove preclude surgical excision. Tissue biopsy revealed primary cardiac lymphoma. After postoperative chemotherapy and radiotherapy, the size of intracardiac mass is decreased in follow up chest CT scan and echocardiogram and symptoms of patient are relieved. Therefore, we report a case of primary cardiac lymphoma with review of literatures.

Cardiac tumors are rare diseases with various imaging findings. However, differentiating cardiac tumors based on imaging findings is challenging because of similarities in imaging features. We present two cases of cardiac tumors, including primary cardiac lymphoma and cardiac metastasis, in which the differential diagnosis was difficult.

Primary cardiac lymphoma, defined as involving only the heart and pericardiwn, is very rare and is diagnosed predominantly late in the course of illness or autopsy. This tumor is commonly fatal and until recently were rarely diagnosed antemortem. Recently, it was reported in patients with acquired immunodeficiency syndrome. We report a case of primary cardiac lymphoma in a 56 year old female who showed progressive exertional dyspnea. On echocardiogram and CT scan, a large ill defined mass was demonstrated in right atrial and ventricular wall. It was diagnosed as B-cell type lymphoma on open cardiac biopsy.

Concomitant Loeys-Dietz syndrome (LDS) and hematologic malignancies are exceptionally rare. This is the first report of a patient operated on for aortic root dilation who had been previously diagnosed with LDS and B-cell-lymphoma. After completion of chemotherapy and complete remission, an elective valve-sparing aortic root replacement (using the David-V method) was performed. Due to the positive family history, preoperative genetic counseling was conducted, and revealed LDS with a TGFBR1 (transforming growth factor beta receptor type I) mutation in 6 probands of the family, albeit in 1 of them posthumously. This missense mutation has been previously described in relation to aortic dissection, but a causative relationship to malignancy has so far neither been proposed nor proven.

A 7 years-old intact female dog (4.8 kg) was referred with primary complaints of enlarged surface lymph nodes, cardiac murmur, coughing and exercise intolerance. Diagnostic imaging studies found cardiomegaly with distended caudal vena cava, marked left ventricular and interventrciular septal thickening and flattening, severe aortic and pulmonic stenosis (~5 m/s), and mitral and tricuspid regurgitation (~4 m/s). Cytology for the samples obtained from submandibular lymph node and left ventricle revealed high grade malignant lymphoma. The case was diagnosed as cardiac lymphoma. The dog was treated with prednisolone (2 mg/kg, PO, q24h), lomustine (80 $mg/m^2$ PO, q3wk), diltiazem (1 mg/kg, PO, q12h) and enalalpril (0.5 mg/kg, PO, q12h). The clinical signs were improved after therapy. The dog is still on the chemotherapy and regularly checked up.

We report a case of a 13-year-old girl with acute lymphoblastic lymphoma- leukemia, who presented with a cardiac metastasis in the right ventricle, resulting in a pulmonary embolism. At the time of her leukemia diagnosis, a cardiac mass was incidentally found. The differential diagnosis for this unusual cardiac mass included cardiac tumor, metastasis, vegetation, and thrombus. Empirical treatment was initiated, including anticoagulation and antibiotics. She underwent plasmapheresis and was administered oral prednisolone for her leukemia. Five days later, she experienced sudden hemodynamic collapse and required extracorporeal membrane oxygenation insertion and emergency surgery. These interventions proved futile, and the patient died. Pathology revealed that the cardiac mass comprised an aggregation of small, round, necrotic cells consistent with leukemia. This is the first known case of acute lymphoblastic leukemia presenting as a right ventricular mass, with consequent fatal acute pulmonary embolism. A cardiac mass in a child with acute leukemia merits investigation to rule out every possible etiology, including vegetation, thrombus, and even a mass of leukemic cells, which could result in the fatal complication of pulmonary embolism.

We report a case of cardiac lymphoma in a 40-year-old man, who had a mediastinal mass which was diagnosed as sclerosing mediastinitis pathologically. The mediastinal mass caused right pulmonary arterial stenosis. The patient developed myocardial hypertrophy and echocardiography showed restrictive physiology and severely decreased left ventricle ejection fraction, 6 months later. MRI showed global left ventricular myocardial hypertrophy and diffuse late gadolinium hyperenhancement after administration of contrast material. Thus, non-ischemic cardiomyopathy was suspected on MRI. However, pathology confirmed the myocardial abnormality as lymphoma after myocardial biopsy. Because a basal part of the left ventricle and global subendocardial myocardium were not involved on contrast-enhanced delayed MRI, the MRI abnormalities could be differentiated from amyloidosis and other myocardial diseases. The peculiar non-mass forming diffuse hypertrophy pattern of cardiac lymphoma has not been known in the MRI literature.

A primary malignant lymphoma that originates in the heart is extremely rare. A 68-year-old male patient was admitted due to aggravated dyspnea. After echocardiography and chest computed tomography evaluation, a huge mass in the right atrium and the right ventricle was detected. We decided to perform emergency surgery due to a high risk of infarction and hemodynamic disturbance. After the near total removal of the huge mass in the right cardiac chamber, the interatrial septum and antero-lateral part of the right atrium were reconstructed by the use of a bovine pericardial patch. The final pathological diagnosis was a primary malignant lymphoma. The patient and his guardians refused chemotherapy (including radiotherapy), and the patient was discharged to his home, where the prognosis was hopeless.

An 11-year-old intact male mixed-breed dog was referred for evaluation of a splenic mass. On radiographs, the cardiac apex, stomach, and head of the spleen were on the right and the descending colon was on the left of the midline. In addition, the left kidney was located more cranially than the right kidney. Standard two-dimensional echocardiographic images were obtained from each inverted left and right parasternal windows. Furthermore, the spleen was observed on the right side and a splenic mass was found on the splenic tail. Based on the radiographic and ultrasonographic characteristics of the patient, a diagnosis of situs inversus totalis (SIT) and a splenic mass was made, and splenic resection was performed successfully with no unexpected complications. The splenic mass was confirmed histopathologically as being marginal zone lymphoma (MZL). This report describes a dog with SIT and splenic MZL.
