title: Azygos vein aneurysm: contribution of transesophageal echography.
abstract: We report a case of idiopathic aneurysm of the azygos vein associated with lung cancer. This abnormality is exceptional because we could find only 8 previous published cases. Computed tomographic scan and especially transesophageal echography were of major importance in identifying the vascular nature of the radiographic abnormality and thus excluding extension of lung cancer.
