Abstract

We report a 36-year-old man who admitted due to brain infarctions of the pons and cerebellum. He had a history of brain infarction 4 years ago. Chest radiograph and enhanced CT showed an abnormal shadow in the superior mediastinum. Chest enhanced CT showed dilated right and persistent left superior vena cava (PLSVC), and venous thrombus was detected in the thorax. The PLSVC connected directly to the left atrium. Abdominal CT showed surface irregularity of the bilateral kidney, suggesting that renal infarctions had occurred. There was no risk factor of systemic embolism except for PLSVC thrombosis. We thought that retention of blood flow caused the formation of thrombus in the PLSVC, and the thrombus flowed into directly the systemic circulation through the left atrium and caused multiple embolisms.<br>
