Multiple Thrombi in the Heart in Trousseau Syndrome Caused by Pancreatic Carcinoma

A 65-year-old woman presented to our emergency room because of sudden onset of right hemiparesis with severe fatigue. Neurological examination revealed right hemiparesis with right facial numbness and an extensor planter response on the right side.Magnetic resonance imaging with diffusion-weighted imaging revealed multiple highintensity areas in both cerebral hemispheres and the right cerebellum. A diagnosis of acute stage of multiple brain infarctions caused by emboli was made. An abdominal computed tomography showed a pancreatic tumor with multiple liver metastases. High D-dimer and serum carbohydrate antigen 19-9 concentration strongly suggested Trousseau syndrome associated with pancreatic cancer. The patient had another large embolic stroke and died on day 47. Autopsy was performed. There were large thrombi in the left ventricular apex and in the left atrial appendage There was also a papillary-shaped vegetation on the aortic valve that consisted mainly of fibrin without any inflammatory cells or destruction of the valve, these findings being characteristic of NBTE. This case is remarkable in that the patient had 3 different types of cardiac thrombi in her heart associated with Trousseau syndrome.
