Background: Diaphragmatic rupture after blunt abdominal injury is a rare trauma condition. Delayed diagnosis is not uncommon especially in the emergency room setting. Associated injuries often shift diagnosis and treatment priorities towards other more life-threatening conditions.
Case presentation: We present a challenging case of a young male with combined abdominal and head trauma. Repeated episodes of vomiting dominated on clinical presentation that in the presence of a deep scalp laceration and facial bruising shifted differential diagnosis towards a traumatic brain injury. However, a computed tomography scan of the brain ruled out any intracranial pathology. Finally, a more meticulous investigation with additional imaging studies confirmed the presence of diaphragmatic rupture that justified the clinical symptoms.
Conclusions: The combination of diaphragmatic rupture with head injury creates a challenging trauma scenario. Increased level of suspicion is essential in order to diagnose timely diaphragmatic rupture in multiple trauma patients.
