ABSTRACT

A 64-year-old woman was found to have an enlarged mediastinum on chest radiography and was referred to our department. One year before the examination, no abnormal shadowing had been found. Contrast-enhanced chest computed tomography (CT) revealed a saccular aneurysm of the azygos vein with a thrombus. We considered surgical resection to be indicated, considering the risk of the patient developing pulmonary embolism. We provided preoperative anticoagulation therapy with rivaroxaban and discovered reduction of not only the thrombus but also the aneurysm. Thereafter, surgery was performed.
We report a case of azygos vein aneurysm with thrombus that developed or increased over the course of one year, in which both the aneurysm and the thrombus diminished with anticoagulant therapy.
