Introduction: pneumomediastinum is defined as the presence of free air around mediastinal structures. It is a rare and alarming radiological finding in the context of polytraumatized patients and its adequate study allows the prevention of potentially lethal injuries. Methods: the case of a 43-year-old male patient admitted in the context of blunt polytrauma is presented. On physical examination, he was found to have subcutaneous emphysema and borderline saturation, with a tomographic finding of pneumomediastinum. Results: esophagogastroduodenoscopy was performed, which was reported as normal and there was no increase in subcutaneous emphysema during follow-up, classifying the case as secondary to the Macklin effect. Subsequently, the patient was discharged in adequate conditions and without repercussions during his hospital stay. Conclusions: pneumomediastinum is a rare but alarming entity that requires knowledge of its causes and study of them in order to prevent potentially lethal lesions.
