title: [Intrathoracic mass in Ewing's sarcoma of the ribs. Apropos of 5 cases].
abstract: 5 cases of Ewing's tumor of the ribs are reviewed. On the initial chest X-ray, they had in common an enormous intrathoracic mass. The bone lesion which was subtle, was hardly seen or missed and the patients were referred to us for investigation of a mediastinal mass, a lung tumor or a pleural effusion. The possibility of a rib tumor was not mentioned. Recent methods of investigation of a thoracic mass include nuclear medicine, ultrasound and computed tomography but the conventional plain chest radiograph is the first and most important test in these cases.
