Recently, it has become not so difficult to diagnose mediastinal tumor or aneurysm of thoracic aorta, because of the remarkable development of the computed tomography (CT). Nevertheless, it can be rather difficult to differentiate thoracic aortic aneurysm from organized thrombus from the mediastinal tumor.
We presented here a case of thoracic aortic aneurysm with organized thrombus who died from the aneurysm rupture. A 70 year-old man was admitted to our hospital with chief complaints of exertional dyspnea and hoarseness. But, Homer's syndrome was not found. Chest X-ray film, CT scan and angiography suggested an anterior mediastinal tumor. But before surgery he died suddenly. Autopsy revealed the ruptured thoracic aortic aneurysm with the organized thrombus, bleeding into the left pleural cavity.
