“…On lateral view, lucent streaks may outline the ascending aorta, the aortic arch, retrosternal, precardiac, periaortic, and peritracheal areas [8, 26]. Other radiographic signs of pneumomediastinum include the “continuous diaphragm sign,” which is mediastinal gas outlining the superior surface of the diaphragm and separating it from the heart [27]. Further, the “V sign of Naclerio,” which is gas outlining the lateral margin of the descending aorta and extending laterally between the parietal pleura and the medial left hemidiaphragm [28], and the “ring around the artery sign,” which is gas surrounding the mediastinal extrapericardial portion of the right pulmonary artery, can be observed [29].…”

Blunt trauma is the most common mechanism of injury in patients with pneumomediastinum and may occur in up to 10% of patients with severe blunt thoracic and cervical trauma. In this case report we present a 24-year-old man with pneumomediastinum due to blunt chest trauma after jumping from a bridge into a river. He complained of persistent retrosternal pain with exacerbation during deep inspiration. Physical examination showed only a slight tenderness of the sternum and the extended Focused Assessment with Sonography for Trauma (e-FAST) was normal. Pneumomediastinum was suspected by chest X-ray and confirmed by computed tomography, which showed a lung contusion as probable cause of the pneumomediastinum due to the “Mackling effect.” Sonographic findings consistent with pneumomediastinum, like the “air gap” sign, are helpful for quick bedside diagnosis, but the diagnostic criteria are not yet as well established as for pneumothorax. This present case shows that despite minimal findings in physical examination and a normal e-FAST a pneumomediastinum is still possible in a patient with chest pain after blunt chest trauma. Therefore, pneumomediastinum should always be considered to prevent missing major aerodigestive injuries, which can be associated with a high mortality rate.

“…The specific signs of pneumomediastinum, are caused by the normal structure outlined by the aberrant air. These include double bronchial wall sign, ring around the artery sign [3], aortic arch sign [3], continuous diaphragm sign [12, 13], extrapleural sign [14], and thymic sail sign [3, 15] (Figures 8(a) and 8(b)). …”

The radiological manifestations of the aberrant air surrounding the pleura are varied because of the air outlining the organs in and out of the visceral space. The continuity of the visceral space from the neck, mediastinum to the retroperitoneum is originated from embryological development, which is compatible with the findings through laboratory experiments, cadaveric anatomy, and thoracic computer tomography image. We reviewed the embryo development to understand the anatomy of body cavity, which can determine the radiological findings of pneumomediastinum and pneumothorax.
