Nonbacterial thrombotic endocarditis, formerly known as marantic endocarditis, it is an infrequent entity in which sterile, fibrin vegetations develop on heart valve leaflets. It is often diagnosed at the time of autopsy or in late-stage malignancies. The most common malignancies associated with nonbacterial thrombotic endocarditis are lung, pancreatic, gastric cancer and adenocarcinomas of an unknown primary site. Diagnosis requires ruling out infective endocarditis and establishing the presence of valvular vegetations using echocardiography. We report the case of a patient with a recent diagnosis of advanced gastric adenocarcinoma who presented with cortical blindness. The computed tomography was compatible with cerebral ischemia. The transoesophageal echocardiogram showed two vegetations in mitral valve. Blood cultures were negative. We emphasize the importance of suspecting nonbacterial thrombotic endocarditis in patients with cancer and systemic embolism.
