Background. Trousseau's syndrome is a blood coagulation disorder associated with malignant tumors. The cause is often nonbacterial thrombotic endocarditis; however, vegetation is often difficult to detect by transthoracic echocardiography. Case. The patient was a 50-year-old woman who visited the hospital with a chief complaint of right-sided neck pain. After a detailed examination, the patient was diagnosed with right internal jugular vein thrombosis, cerebral infarction, and lung adenocarcinoma. Transthoracic echocardiography, which was performed to determine the cause of the thromboembolism revealed vegetation on the aortic valve, and the patient was diagnosed with Trousseau's syndrome complicated by nonbacterial thrombotic endocarditis. The patient was treated with systemic chemotherapy and anticoagulation therapy, and the lung adenocarcinoma and thromboembolism improved. The performance of transthoracic echocardiography enabled us to monitor the disappearance of the vegetation over the course of treatment. Conclusion. We encountered a case in which we could ascertain the state of Trousseau's syndrome with transthoracic echocardiography.
