title: An unusual case of bronchial rupture--pneumomediastinum appearing 7 days after blunt chest trauma.
abstract: We present a case of bronchial disruption after blunt chest trauma, which is unusual because the pneumomediastinum on the chest radiograph was detected 7 days after the injury. The first day imaging methods of the thorax showed only the fractures of the first and third left rib without any complications. A computed tomography (CT) scan was done following control chest radiograph and it revealed a rupture of the left main bronchus with pleural effusion, subcutaneous emphysema and pneumomediastinum. This case shows that a finding of pneumomediastinum after blunt chest trauma should always merit further investigation of its cause, even in cases of postponed detection of pneumomediastinum and regardless of the absence of other indicators of tracheobronchial disruption. Although fiber-optic tracheobronchoscopy is considered a diagnostic golden standard, in this case, diagnosis was clearly confirmed by spiral CT scan, due to thin slices and continuous data acquisition.
