Blunt trauma resulting in pneumothorax with progression to pneumoperitoneum: a unique diagnosis with predicament in management

Here, we present a case of pneumoperitoneum caused by traumatic pneumothorax after a fall. The patient is an 82-year-old male who was brought into the emergency department after being found at the bottom of a flight of stairs with a bleeding scalp laceration. Upon presentation, the patient underwent emergent intubation followed by tube thoracostomy placement, had necessary imaging and was transferred to the surgical intensive care unit (SICU). Imaging revealed signs of pneumomediastinum and pneumoperitoneum in addition to the partially resolved pneumothorax. In the SICU, the patient became hemodynamically unstable requiring vasopressor support, which in the face of documented pneumoperitoneum without a clear cause mandated exploration. He was taken to the operating room for suspected viscus perforation, though none was found after extensively searching during an exploratory laparotomy. We suspect the patient developed pneumomediastinum and pneumoperitoneum as a result of traumatic pneumothorax, hastened by his subsequent intubation and mechanical ventilation.
