Traumatic diaphragmatic hernias were first described by Ambroise Paré in 1579, who reported the case of an artillery captain, that presented an intestinal perforation that had caused a diaphragmatic hernia (Bhatti and Dawani, 2015). The timely diagnosis of a traumatic diaphragmatic hernia can be a challenge, which requires extensive knowledge of the kinematics of trauma, as well as clinical and radiological evidence (Petrone et al., 2017). We present the case of a 60-year-old male who presented blunt abdominal trauma due to a traffic accident, causing an undetected diaphragmatic hernia in his initial evaluation; months after de incident goes to the emergency room (ER) with hemodynamic instability and septic shock. A diagnosis of complicated diaphragmatic hernia and fecopneumothorax is made, for which he undergoes surgery.
