A mobile thrombus in the ascending aorta is extremely rare. A 57-year-old man was referred to our hospital with suspected esophageal cancer. Following thorough evaluation, he was diagnosed with esophageal cancer (UtMt type0-Ⅱa T1b, Mt type0-Ⅱc T1a N0M0 cStageⅠ) and tongue cancer in situ. He was administered preoperative chemotherapy comprising fluorouracil and cisplatin. The patient developed fever on day four of the first course of the chemotherapy. Contrast-enhanced chest and abdominal computed tomography revealed a mobile thrombus in the ascending aorta with bilateral partial renal infarction. We initiated intravenous unfractionated heparin and oral warfarin as anticoagulant therapy. The thrombus did not disappear despite ten-day treatment;therefore, he underwent aortic thrombectomy under hypothermic circulatory arrest with retrograde cerebral perfusion. Intraoperatively, we detected a pedunculated mobile thrombus attached to the aorta. His postoperative course was uneventful and he was treated at discharge with warfarin. He underwent video-assisted thoracoscopic esophagectomy postoperatively and was discharged without any complication. Currently, he showed no recurrent thrombus or cancer.
