[A Case of Trousseau Syndrome Associated with Advanced Rectal Cancer].

We report a case of Trousseau syndrome associated with advanced rectalcancer. A 67-year-old man visited our hospital for right hemiparesis and gait disturbance. Head magnetic resonance imaging showed multiple cerebral infarctions. Abdominal computed tomography showed wallthickening of the rectum and colonoscopy showed type 2 circumferentialrectalcancer. Therefore, he was diagnosed with Trousseau syndrome. After anticoagulation therapy with heparin, an operation was performed. Thereafter, chemotherapy was continued and he has experienced no recurrence of cerebralinfarction.
