title: Diffuse Subcutaneous Emphysema and Pneumomediastinum Secondary to a Minor Blunt Chest Trauma.
abstract: Full medical evaluation is paramount for all trauma patients. Minor traumas are often overlooked, as they are thought to bear low injury potential. In this case report, we describe the case of a 48-year-old man presenting to our Emergency Department with mild to moderate right-sided shoulder and scapular pain following a fall from his own height ten days previously. Clinical and paraclinical investigations (CT) revealed diffuse right shoulder pain, with crepitations on palpation of the neck, right shoulder, and right lateral chest wall. Computed tomography (CT) demonstrated right-sided costal fractures (ribs 7 to 9), with diffuse subcutaneous emphysema and pneumomediastinum due to laceration of the visceral and parietal pleura and the adjacent lung parenchyma. In addition, a small ipsilateral pneumothorax was found. Surprisingly, the clinical status was only minimally affected by mild to moderate pain and minor functional impairment.
