[Cerebrovascular complication in non-bacterial thrombotic endocarditis. Value of cardiac transesophageal ultrasonography].
BACKGROUND: Non-bacterial thrombotic endocarditis in patients with cancer can lead to ischemic stroke. Endocardial vegetations are usually small and may be missed at transthoracic echocardiography. CASE REPORT: Disseminated intravascular coagulation developed in a woman with ischemic stroke. Transthoracic echocardiography was normal. Four days later, transesophageal echocardiography revealed a large mitral vegetation suggesting non-bacterial thrombotic endocarditis. The diagnosis was confirmed at pathology which reported carcinoma of the colon. DISCUSSION: Transthoracic echocardiography is rarely contributed to the diagnosis of thrombotic endocarditis. In our patient transesophageal echocardiography grave the diagnosis before death instead of retrospectively at autopsy as usually occurs, demonstrating the value of transesophageal echocardiography for cancer patients who develop ischemic stroke.
