False aneurysm secondary to aortic cannulation--rupture into lung with fatal hemoptysis during aortography

We report a case of fatal rupture of a false aneurysm of the ascending aorta during aortographic injection. The aneurysm had formed at the site of aortic cannulation done for a cardiac bypass at an earlier date. The rupture manifested as hemoptysis as the false aneurysm had burrowed and ruptured into the anterior segment of the right upper lobe of the lung.
