title: Saccular aneurysms of the thoracic aorta.
abstract: In the evaluation of thoracic masses adjacent to vascular structures, aneurysms must be considered as a possible etiology. Particular consideration must be given to this possibility before percutaneous biopsy is performed. While contrast-enhanced computed tomography or magnetic resonance imaging is usually sufficient for making the diagnosis, angiography remains the gold standard for characterization and preoperative planning.
