title: [Round shadows in the thoracic roentgen picture, nicotine abuse].
abstract: A 69 year old male patient was seen at our outpatient clinic because of a paravertebral mass in the routine x-ray-film of the chest. The patient was in good health, showed no loss of weight and complained only of slight cough probably due to his smoking habits. In view of these findings a benign lung tumor was suspected. However, the computed tomography of the chest revealed an aneurysm of the descending aorta which was successfully operated.
