A 69-year old Japanese woman with hypertension was admitted because of continuous back pain and recurrent hemoptysis. Radiographic findings showed an enhanced irregular mass, at the aortic arch fed by the tracheal artery, which implied both a penetrating aortic atherosclerotic ulcer and lung cancer. Diagnostic surgery revealed no evidence of cancer but did reveal a rupture of the intima at the distal part of the aortic arch. It is assumed that the transmural oozing occurred after development of the penetrating aortic ulcer, which formed an extra-aortic hematoma and caused surrounding inflammation, and led to tracheal artery feeding. The intramural hematoma might have weakened vascular wall tension from the aorta, and formed an oozing extra-aortic hematoma instead of an acute rupture.
