A 50-year-old man exhibited progressive bilateral claudication. Imaging revealed a suspicious intramural lesion with no significant enhancement on positron emission tomography\u2013computed tomography scans. Because primary aortic angiosarcoma could not be excluded, an oncological surgical strategy was used. The lesion was removed en bloc without luminal entry, and a 22-mm Dacron graft was used for reconstruction. Histopathological analysis confirmed thrombus without malignancy. Postoperative recovery was uneventful, with resolution of claudication, normalization of the ankle-brachial index (ABI) and ongoing cytoreductive therapy for confirmed essential thrombocythaemia. This case highlights the importance of considering haematologic disorders in aortic pathology and demonstrates a safe surgical strategy in diagnostically uncertain cases.<\/jats:p>","DOI":"10.1510\/mmcts.2025.025","type":"journal-article","created":{"date-parts":[[2025,5,7]],"date-time":"2025-05-07T14:22:42Z","timestamp":1746627762000},"source":"Crossref","is-referenced-by-count":0,"title":["Descending aortic stenosis caused by intramural thrombus in the setting of severe thrombocytosis: a rare mimicker of aortic angiosarcoma"],"prefix":"10.1510","member":"10966","published-online":{"date-parts":[[2025,5,7]]},"container-title":["Multimedia Manual of Cardio-Thoracic Surgery"],"original-title":[],"deposited":{"date-parts":[[2025,5,7]],"date-time":"2025-05-07T14:22:42Z","timestamp":1746627762000},"score":1,"resource":{"primary":{"URL":"https:\/\/mmcts.org\/case-report\/2019"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,5,7]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1510\/mmcts.2025.025","relation":{},"subject":[],"published":{"date-parts":[[2025,5,7]]}}}
