Primary cardiac lymphoma (PCL), defined as a lymphoma clinically mimicking cardiac disease, with the bulk of the tumor located intrapericardially, is extremely rare in immunocompetent patients. Clinical manifestations vary depending on sites of involvement in the heart and include chest pain, arrhythmias, pericardial effusion, and heart failure. Diagnosis is often difficult and may require invasive procedures; in some cases, diagnosis is not made until autopsy. Histologically, nearly all cases of PCL reported thus far have been of B-cell origin. In this report, we describe a case of PCL of T-cell origin in an adult immunocompetent patient, the second reported in the literature to the best of our knowledge, and provide a brief overview of the features of previously published PCL cases.

Two-dimensional transthoracic echocardiography is commonly performed to detect a possible cardiac source of systemic embolism and it has been the mainstay of detection and diagnosis of cardiac masses. The transesophageal approach has enhanced the ability to detect cardiac sources of embolism by allowing a better visualization of posterior cardiac structures such as the left atrium with left atrial appendage, pulmonary veins and thoracic aorta and by providing higher resolution images to improve assessment of the presence and extent of cardiac masses. In this case report, echocardiography, using both transthoracic and transesophageal approach, allowed to detect a neoplastic mass arising from the upper left pulmonary vein in a patient presented with a transient ischemic attack. Further investigations showed a malignancy involving the lung. To our knowledge, this is the first reported case in which a cerebral embolic episode represents the clinical onset of a lung cancer, pointing out the importance of echocardiography in all cases of undetermined cerebral ischemic attack.

In patients with acute chest pain, the occurrence of multiple cardiovascular risk factors adversely affected CFR in an additive manner, in absence of significant angiographic stenosis. Diabetes mellitus was a powerful coronary risk factor decreasing CFR both in patients with or without significant LAD disease.
